4.9/5 - 1220 Reviews

Read some helpful reviews of Extra Space Storage at 9363 East Southern Avenue, shared by real renters with genuine experiences and honest opinions.

Right from the start, I was desperately looking for outside storage in the process of moving from one location to the next. I called several companies, some answered the phone after several phone tree buttons later, some I was only able to leave a message with no return call and others didn’t pick up at all because it was on a Sunday. That’s when I called your company from the number on the website. They were immediately responsive answering all my questions, helped me find the closest location and even had questions for me that I hadn’t thought about. Very helpful! While I was still on that first call, Tyler Schwenk called me, from Southern Ave in Mesa, AZ, the location I had chosen. Tyler stayed on the phone with me as I completed the application and the same day. I was able to bring my first load over. The following day, I received another call from Tyler asking if I had been able to access my unit, and if there was any other way he could assist. For the short time, I used your facilities, Tyler was very attentive, knew me by face and name, and always offering his assistance! The facility itself was very secure, clean and well lit. Hopefully, I will not move again, but if I did, I would certainly go straight to your company. I highly recommend Extra Space Storage to everyone I know! Warm regards, Rebecca Messreni ... Read more

Tyler Schwenk delivered outstanding support, assisting me in getting settled into my storage unit and walking me through the step-by-step process of adding the Extra Space Storage app. Right before I departed to proceed to my storage unit, he displayed remarkable courtesy by offering water on a very hot Arizona spring day. Thank you, Tyler, for your fantastic hospitality, which created a warm and welcoming environment. God bless. ... Read more

Been a customer here for almost a couple years now and they have always taken care of me here. Great units, clean community spaces, and affordable high quality units. The manager Tyler is a gem and highly helpful. Highly recommend going through him for all your needs here. ... Read more
John L. - 14 February 2026
Highly recommend. Managed by a great site manager Tyler. This alone made my experience. He was often available including when I opted to upgrade my access to 24 hours. Signup was easy and almost completely hands off. **Site is clean and meticulously maintained** It is within locked gates and code locked buildings. So long as you had one of the specific locks that are used for these units from a previous unit you were allowed to provide your own. Manager was very professional and reached out immediately upon signup to make sure I was able to get into the unit. After experiences with other companies throughout the years, this was hands down my best experience. ... Read more
Ben H. - 11 February 2026
Tyler and Savannah were both very easy to deal with and made an effort to handle any issue presented to them. One of the things I was very impressed with was how clean the entire facility was from the front office to the storage units themselves. My only criticism would be that the app was not reliable. ...

I have been utilizing these storage units for approximately a year and have had to switch units and coordinate with the front office on multiple occasions. The facility is consistently well-maintained, and the staff is always professional and courteous. Hector, in particular, has provided exceptional assistance on numerous occasions, demonstrating a high level of professionalism and customer service. I highly recommend this storage facility. ...

These amenities include Climate-Controlled, Indoor, 24 hour access, Drive-Up Access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, Credit Cards Accepted, Elevators, Multi-Level Storage, Online Payment and RV Storage. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Extra Space Storage - 9363 East Southern Avenue can satisfy all of your storage needs. Different sizes here range from 25 to 600 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Extra Space Storage - 9363 East Southern Avenue come at a variety of prices, starting from $36 per month for typically smaller units. However, larger spaces can set you back up to $422 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
