Just wanted to give a huge shout-out to Karen! She was absolutely amazing in helping us get settled into our new units. We've got two climate-controlled spaces, which is fantastic, and Karen walked us through everything – insurance, gate codes, the whole shebang. She really went above and beyond to make sure we felt right at home. The whole moving-in experience was so much smoother thanks to her! ... Read more

This facility is by far the best I have dealt with. I had a unit here for 3 years. During this time I never had an issue with tampering to my unit. The staff here is amazing. They will do anything and everything in their power to ensure you are taken care of including giving you personal calls for reminders. I would give a higher rating if there was one. Highly recommend Raul and Ruben!! ... Read more

A-AAAKey Mini Storage On Grissom and Tezel is amazing. Not once have I had a negative experience. Anytime I have a question whether it be about my payment method, switching units, or replacing storage keys they are always ready to help. The Storage follows the posted hours of operation at all times. I would like to note that I feel safe visiting my storage and keeping my belongings there as there is property manager onsite at all times as well as security cameras throughout the whole property! ...

This particular storage facility provides self storage units of different sizes, ranging from 25 to 300 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 A-AAA Key Mini Storage - 9120 Grissom Road start from $55 and can go up to $325 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.
