Read some helpful reviews of AAA Storage at 100 Triad South, shared by real renters with genuine experiences and honest opinions.

AAA Storage is well-run administratively, well maintained and secure for your personal storage needs. It has a wide variety of storage unit sizes available to suit your individual needs. The staff discussed with us about types of items we would be storing to determine the right size unit appropriate for us. The staff was very upfront about the rates and terms of the agreement, payment methods, etc. So there were no surprises when completing the contract. We were able to select a unit, not just assigned one. Our unit was swept out and ready to go when we were ready to take possession. Leanna and Barbara were a pleasure to work with! I would recommend this business to anyone needing extra storage. ... Read more

Went to go rent a 10×10 unit (J7) and measured it with a taoe measure, it was 8ft4in deep by 10ft wide. I told the desk this and that I didn't want to pay a 10×10 price for an 8×10 unit and they told me they weren't a good fit then. She told me she couldn't reconfigure the units, I wasn't asking her to, but I think you should be honest about the size. She even tried to argue with me before I stated I measured it the correct way. I also looked at some other sized units a week or so prior and noticed that the measurements on other units seemed off too by just walking them out, but this time I brought a measuring tape to confirm the size. Be sure to measure before renting and look elsewhere because they are falsely advertising their units. I went to a competitor and their unit sizes matched the description for comparable prices. Edit: In response to the reply, the side that is 8ft long was not the side with the door on it, I measured the wall by the side of the door to the back wall, it was 8ft4in. Side to side was accurate at 10ft. I went to a competitor and measured the same way I did yours and theirs measured 10×10. I know how to measure. And actually the first time I came in I never mentioned the sizing being off to you, in fact, I just left after looking at them and doing a estimation measure with no comment. Today was the first time I mentioned the measurements were off. I just think you should be honest with customers about sizing and encourage people to measure before buying just to make sure they get what they are paying for. Also, the $85 a month is the sale that has been going on for the past month and was not offered in response to my complaint. The "sale price" of $85 is around the price of the competitors, and the regular $130 is far exceeding any competitor pricing. ... Read more

I’ve had this unit since 2017 and it’s been one thing after another with the roof leaking into my unit and having water damaged containers. Then locking my unit because I missed the first day of payment. I make the payment but, this lady is so lazy refuses to open it for me because “we close in 5 minutes”. Find a unit somewhere else folks, this place does not take care of their buildings maintenance needs. ... Read more

Leanna is very friendly, outgoing and knowledgeable about the different size storage units and what our needs were. When we were done with business it felt like Leanna was a long time friend! Thank you for welcoming us to the community and we look forward to seeing you. ... Read more
Chris K. - 20 October 2024
I have had a unit at AAA for 5 years. I love being able to store all my seasonal decorations here. When my son was able to take some of his items out of my unit, the staff was very accommodating letting me move to a smaller unit. I love the location, as well as the setup within the coded gate. ...

Frequently Asked Questions

There is a wide array of amenities available for the storage units that AAA Storage - 100 Triad South has to offer. These amenities include 24 hour access, Drive-Up Access, Retail Available, Onsite Manager, Security Camera, Gate, Parking, Credit Cards Accepted 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 AAA Storage - 100 Triad South can satisfy all of your storage needs. Different sizes here range from 36 to 275 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 AAA Storage - 100 Triad South come at a variety of prices, starting from $65 per month for typically smaller units. However, larger spaces can set you back up to $250 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!
