Read some helpful reviews of Mini U Storage at 3450 South Congress Avenue, shared by real renters with genuine experiences and honest opinions.

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

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

This particular storage facility provides self storage units of different sizes, ranging from 25 to 200 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.

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.
