Read some helpful reviews of Extra Space Storage at 12390 Arnold Mill Road#C, shared by real renters with genuine experiences and honest opinions.

Amazing service by the onsite manager Diego. Truly one of the most coolest managers Ive ever met. Always ready and willing to help as well as being incredibly easy to talk to. Highly recommend My only note to higher ups within Extra Storage. If im paying for a space, i should have 24/7, 365 days a year access to my unit. No hours should prevent me from being able to load in/our of the storage space. Diego, great! No 24/7, awful ... Read more
Devin E. - 10 March 2026
This is a great storage unit as there is always someone in the office during standard working hours. If it is outside of their standard hours you can always speak to someone on the phone. The facility is clean and well it. The management is responsive and always addresses any matters that you raise. ... Read more

Nick F. - 20 June 2025
I contacted Extra Space Storage because my present storage company Has no one on site to handle issues and is self service/kiosk only. The first person I spoke with, was very easy to talk with, and we worked out a great deal. I then spoke with Veronica, who was very helpful and finally with Connor, the property manager. Everything has been very smooth. They've accommodated me with a space that's easy to load in because of the location and convenient. I look forward to a long relationship with this property! ...

George S. - 24 April 2025
I have had a unit with Extra Space for almost three years, when it was still Life Storage and it was a smooth transition. I have never had any issues and I would recommend their services to others. Veronica and Troy were the only employees I have had encounters with and they were always friendly and helpful. ... Read more
Kei T. - 4 March 2025
1. I rented a unit for less than $40/month with life storage. Then Extra Space bought the life storage. I think the Extra Space just want more money from their good customers, the company raised my monthly rate to more than $70 after 3 months! There was no emails, no phone calls and no text messages in advance to warn me the rate increase. 2. No prorated refund when I moved out after 10 days of the billing date. ... Read more

Brian R. - 16 February 2025
Had a great experience with this facility. Connor was so friendly and broke everything down for me in a very transparent way. Even though I’ll be renting at a different location (with Marva, who was so helpful!) I’d recommend this storage facility to anyone! ... Read more
Kim C. - 14 February 2025
When we moved into this storage facility, Connor, the manager, made everything so much easier. He listened to what we needed and went above and beyond to help us find the perfect unit. Connor ensured we had a space that was just the right size and easy to access, making the whole process feel seamless. His dedication to making sure we were satisfied was evident every step of the way. 10/10—Connor is an amazing manager who truly cares about his customers! ... Read more

Frequently Asked Questions

Depending on what you need to put away in storage, you can discover there are some things you absolutely need, so make sure you check with the facility manager that you'll find everything you need on site.

This particular storage facility provides self storage units of different sizes, ranging from 25 to 400 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.

You already know how much stuff you need to put in self storage, so figuring out the unit size you need is the next step. 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. Finally, a 10'x20' unit has enough space for the contents of a 3-bedroom house, while the larger 10'x30' space easily accommodates the contents of a loaded semi-truck.

Monthly prices for units offered by Extra Space Storage - 12390 Arnold Mill Road#C start from $41 and can go up to $322 for larger spaces.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient. Pull your car right up to your storage space, load, unload, and you're good to go! However, if you're mostly storing temperature-sensitive items, you should rather consider indoor storage units.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items. Moisture and varying temperatures can damage a whole host of things, and that is why a lot of people choose to use climate-controlled units to store items like wooden furniture, electronics, artwork, documents and photographs, collectibles, antiques, etc. If the belongings you're storing are important to you, you should consider renting a climate-controlled unit.
