    We have been using storage units for years. This one by far is the friendliest, cleanist, knowledgeable anf helpful people we have encountered. When we. Eet Carrie and Charles it felt like we’ve known then for years. This couple is an asset to the company. It was a no brainer to rent from them. It was because of them, we chose Mini U Store. Didn’t even check put other storage places. Thank you Carrie and Charle for the besr customer service we have received from any other vendor. God bless. ... Read more

    The cleanest storage place I have ever been too! Charles and Carrie run the place and they are great, two of the nicest people I've ever met. I always feel safe there. They have great security, their gates are always working the place is always clean and lights are always working in the building, and you will never find anybody sleeping or living in the units. You never see bugs or rodents, which for me is very important, and they lend you a box truck when you move in which is a really nice bonus. ... Read more

    The staff, including Charles and Carrie, are very friendly and helpful and very knowledgeable of what they’re promoting. very tight with their premises. The premises itself is very clean and secured. One of my past experiences with another local storage company was their roads were very hazardous. They had potholes all over the place. There was nails everywhere so I literally had to change my tire about four times within a few months at a previous location but over here it looks like a brand new store but honestly it’s been around since the 90s. I definitely recommend to keep your storage stuff. their rates are fair and competitive. so with competitive rates they are offering high-quality storage facilities. ... Read more

Also, appreciated the transparent nature and upfront disclosures of costs and potential increases, no bait and switch types of dealings here compared with other storage facilities we’ve used in the past. ...

    My husband and I rented a unit this past Sunday. Charles is extremely helpful and the process is quick. We had reserved the truck for a future date before we left, however, we received a call within a hour from Carrie after because the truck was not available for that date, She was not in the office at the time we were there and apologized its unavailability because it was getting serviced that day and was not put on the calendar. We quickly booked a new date. Both Charles & Carrie are very helpful and easy to work with. The units are clean, the grounds are well maintained, safe & secure. If you need to rent storage space, I highly recommend Mini U Storage(Boynton Beach) ... Read more
