Stefalonikus M. - 18 August 2025
Called and left a message with details as asked according to the voice mail. Soon after, within 15 minutes I received a call from Rebecca. She was polite, professional and prompt. Had my storage unit ready in about an hour. She explained everything and asked if I needed any special accommodations or anything. Her customer service is top notch. I hope the owner appreciates her because I will recommend this location as long as Rebecca is there to manage the business. ... Read more

Rebecca, the property manager, was informative and patient with the children. She offered a great rate, and the transaction was quick and easy. This is my second visit, and the location is always clean. ... Read more

Unit was broken into, they bypassed the lock by cutting the loop around the lock. These things happen and I understand. However, the manager Rebecca was extremely unhelpful. They could see who it was but seemed helpless to do anything. The same person, again on camera, broke in again less than 24 hours later. Managers' advice was that it would be best if I moved out again appearing helpless, they have the person on camera. The police apparently are as helpless as the manager. If you are a veteran and or a senior as I am I recommend against storing here. ... Read more

The storage units offered by A-AAA Key Mini Storage - 6604 McDermott Freeway I-10 Road 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.

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!
