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

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

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

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. ...

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

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

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

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
