This is a great facility. Easy in. Easy out. Great space options to select from. Incredibly clean and well maintained. The employees are fantastic. Tiffany is helpful, knowledgeable, and always welcoming. With so many storage sites to select from in the Valley, this one is definitely at the top of the list.

This is a great storage. I highly recommend it.. The store manager,Tiffany is excellent. She’s always extremely accommodating, respectful and knows how to do her job. I definitely choose the storage place over any other in this area.

Justin P was very pleasant and professional. He was a pleasure to work with. We received all discounts available and he did it in a quick and efficient manner.

Rental process was extremely easy. Everything was done online. After signing contract, a Welcome message was sent to me with all the details and codes to access the storage location. The manager, Justin, followed up with a phone call to see if I had any questions. My unit is indoors. Everything is clean and well maintained. No dented walls or trash 🚮 n the hallways. I highly recommend this CubeSmart!
