Read some helpful reviews of Extra Space Storage at 5815 Arapahoe Avenue, shared by real renters with genuine experiences and honest opinions.

Casey W. - 9 March 2026
Geraldine was super sweet and super helpful! I came in late in the evening and she went out of her way to make sure I could get my unit before the night was over instead of having to wait till the next day! ... Read more
Courtenay K. - 11 February 2026
When I signed up for my storage unit, I was given a rate of $120 a month. After 3 months of storage, the rate jumped up to $220 without notice (they say they mailed me a 30 day notice but I never got it, and why would they mail me a notice when all of our other communications have been via email?). They’re basically running a scam in which they get you to sign up for a rate that feels fair, let that price sit for a few months and then they suddenly jack up the rate by 80%. I’m moving my property out of here promptly. ... Read more

I walked into Extra Space Storage on Arapahoe on what was easily one of the worst weeks of my life. Within seven days, I’d lost my job, torn something in my leg at the gym (crutches included), and my dog (my best friend) had gone missing. My apartment was chaos, my head was worse, and I needed to store my belongings because I genuinely didn’t know what the next month of my life looked like. Enter Geraldine. From the moment I walked in, she didn’t treat me like a transaction, a unit number, or a problem to process. She treated me like a human being who was clearly having a hard time. She slowed down, listened, asked thoughtful questions, and somehow struck the perfect balance between professionalism and real compassion. She went way beyond what her job requires, explaining options clearly, helping me find exactly what I needed (not what cost more), and making sure I felt confident and taken care of at a time when I felt anything but. She noticed the crutches. She noticed the stress. And instead of ignoring it, she met it with kindness. I didn’t walk out with just a storage unit, I walked out feeling calmer, steadier, and honestly… a little more hopeful. That may sound dramatic for a storage facility, but when someone shows up with genuine care during a low point, it matters. Geraldine is the definition of exceptional customer service. Not because she followed a script, but because she saw me. If every business had someone like her at the front line, the world would function a whole lot better. If you’re considering Extra Space Storage, know this: you’re in very good hands if Geraldine is there. ... Read more
Scott R. - 16 January 2026
The staff waiting on me today at Extra Space Storage were suburb. He answered all my questions and did his best to show me the storage facility before I signed the lease (he did not have a key to the unit). I would have given 5 stars if the review only reflected the attention from staff - however, one star is subtracted given the inability of the business to provide better lighting in the storage areas, and the rather sketchy area surrounding the storage unit location. Hopefully the use of this unit will prove to be as good as the staff appear to be. ... Read more
Kathleen O. - 11 October 2025
Geraldine, my location’s facility manager is exceptional. I know she’s having a hard time with staffing and many times she was having to be in a hundred places at once! Today’s reality is tough and she’s handling her own the best she can. She went over and beyond to help me with my needs and accommodations including an after hours issue on location. Head over and introduce yourself and share your storage needs with her and she will take care of you for sure! ... Read more
Krista R. - 7 October 2025
Great experience. Was really easy. I started my account online and was able to store my stuff immediately after business hours on a Sunday. Got a code and could get in immediately. Move out process was quick and easy. When I was done the staff was friendly and extremely helpful and made sure my account got closed properly and the lock that I didn’t use was refunded. ...

Junebug Q. - 25 July 2025
63rd Street location has decent facilities - concrete block walls and better-quality, functional garage doors. Staff was generally courteous and helpful. Pro Tip: Storage companies lure you in with low rates and then increase them rapidly after you have moved in, with increases of 20+% not uncommon. My last increase at this facility was north of 30%, which seemed egregious and compelled me to depart. Storage companies can do this because many people are unwilling to go through the pain of moving their belongings to new storage facility and instead choose to pay the higher rate. The hack is this… many storage companies will allow you to prepay your rent. If you have the ability to do so, you can prepay and lock in the low rate for the period of time you know you will need the facility. Something to consider, again if you have the means, to avoid such unconscionable rate increases. Good luck! ... Read more
David N. - 25 July 2025
This storage unit has been top notch. I love the accessibility of the gate through the app. There has been strong communication regarding changes or notifications by the staff. The units are clean, safe and affordable. The staff is incredibly nice and helpful. ... Read more
Brionna G. - 8 July 2025
Geraldine, and the entire team at extra space Are amazing! As a mom trying to handle many moving parts for a student, Geraldine's guidance and navigational skill were worth their weight in gold! If you want to do business with people who have integrity and local savvy, Extra space is the spot! ... Read more
Angelique S. - 1 July 2025
The location is well-maintained and the storage space itself was a good size. Check in and check out is relatively simple. Felt very secure. The staff is very responsive and helpful, shoutout to Peter for being extra kind and careful with my locker and solving my concerns very quickly. Just a heads up, you aren’t allowed to dump anything on the property so if you are planning to clean out your locker have a plan on where to properly dispose of your items! ... Read more
Veronica S. - 19 April 2025
Planning for summer storage for my college student and just signed up with Extra Space Storage. New account setup was quick & easy through the 866 number. A little while later I needed to change my contract and they forwarded me to Peter at the Arapahoe/Boulder location. He was patient, understanding and emailed the new contract while I was on the phone with him. Peter, you’re a rockstar! Thank you for making this easy! ... Read more
Myra B. - 14 March 2025

The facility and grounds are extremely clean and well cared for and the level of security gives you peace of mind when storing your things. The rental process was so easy and the folks running the office are kind, thoughtful and take the extra step to ensure you are set up successfully.

A huge thank you to Extra Space Storage, you guys are amazing! I arrived needing a storage unit for my belongings after bringing them halfway across the country, and Geraldine made the entire process seamless and stress-free. After renting for a couple of months, I can confidently say the team here has been incredibly helpful. I may have just found the perfect long-term spot to store my belongings! ... Read more
Djason A. - 4 February 2025
My experiences with Extra Space Storage have always been fantastic. I'm currently in the process of moving storage units, but I couldn’t make it today to move my things. When I called to let them know, they were incredibly flexible and understanding. Peter, who I spoke with, was a tremendous help! He provided all the information I needed for my move tomorrow and went above and beyond to reassure me. His kindness, patience, and sense of humor made the whole situation much less stressful. I truly appreciate the excellent customer service! ... Read more

This particular storage facility provides self storage units of different sizes, ranging from 25 to 500 square feet. Space is not an issue! If you have more belongings to store, or simply bulkier items or even vehicles, you should go for larger storage units.

Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.

Moving on to larger sizes, imagine the 10'x10' and 10'x15' units as similar to a bedroom or a living room – larger pieces of furniture, sturdier equipment and bicycles can fit here.
