Amazing and friendly staff! My daughter and I had trouble finding the right storage for our items and I found a storage with 2 doors on it! This place is a must for storage unit..... This was posted yesterday when I purchased the unit for a free lock, when I arrived this morning a car was at the gate so I waited, when the car pulled forward I also pulled forward slowly and waited for the gate to close as it was almost closed it began to open again as I started exiting my box truck. I looked in the window and seen the new manager from the Colorado and I-70 store and thought he opened it since I was here to meet him for 2 shelving units I was renting from them. I drove forward and turned off my box truck and started walking towards him. He immediately became hostile and I was trying to explain to him I thought he opened the gate and he still remains hostile. This guy Definitely hates his job and residents. Please if you value your money, respect as a customer, or valuable property please avoid this location at all costs. Not mini u storage just this exact location. Thank you ... Read more

Unit was filthy. Mouse droppings everywhere and spider webs. Trash. And the back gate was wide open the whole time i was there. Doesn't seem secure. The gentleman that works there was funny and helpful so I will give more than 1 star because that's not so common sometimes these days. The price was def the best around also just FYI. I backed out and had no problem receiving my money back in a few days. ... Read more

I’ve been had a storage for much longer than I care to admit, but Mini U Storage has been a delight to work with. They have always been extremely understanding regardless of the situation and they communicate effectively! I am happy to say I’ll be moving my things out at the end of this month, but I appreciate all you have done for me in keeping my most precious valuables. Thank you! ... Read more

Depending on what you need to put away in storage, you can discover there are some things you absolutely need, so make sure you check with the facility manager that you'll find everything you need on site.

This particular storage facility provides self storage units of different sizes, ranging from 25 to 600 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.
