    Read some helpful reviews of A-AAA Key Mini Storage, shared by real renters with genuine experiences and honest opinions.

    I've been with AAA key mini storage for years and the experience is tremendous. They always give you a notice if there is something that they are working on on the property. The accessibility is during their business hours and beyond. The price is exactly what it should be. The property is always clean. The management is very respectful of my unit. They always communicate well if there is an issue regarding my unit. They have recently gone to a automatic withdrawal policy and so this makes paying the monthly bill very easy and efficient. There's always someone in the office if you need to talk to them. I highly recommend AAA key mini storage for anyone who needs to have a place to store their personal items. ... Read more

    I love the location on I-10 at crossroads. It is always clean fully accessible and customer service is outstanding. So far the rate has remained the same which I'm hoping it continues to. I have plenty of room in my storage and overall I'm very happy. ... Read more

    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
