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

Catherine M. - 29 March 2025
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

Frequently Asked Questions

There is a wide array of amenities available for the storage units that Mini U Storage - 3450 South Congress Avenue has to offer. These amenities include Climate-Controlled, Drive-Up Access, Retail Available, Onsite Manager, Truck Rentals, Security Camera, Gate, Parking, Credit Cards Accepted, Online Payment and RV Storage. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

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!
