Josh was not helpful and was very rude when assisting my mother and I with switching storage units. We tried to explain an issue we had with one of our storage units and he wasn't understanding it. We arrived at the office over an hour before closing time but it took time trying to explain our situation and to try to get it fixed. About 15 minutes before closing time, he told us that he was getting frustrated and that it was almost closing time which was very unprofessional. We tried to politely explain what exactly had happened but we ourselves were getting frustrated by the mistake done by the office that wasn't getting resolved. He ended up rudely kicking us out and telling us to come back the next day. He was overall very rude, unhelpful and pushed us out the door without helping solve the mistake that was done by the office. We went back the next day and were helped by Danny. He understood exactly what our issue was after we explained it and quickly worked to resolve it. He was very nice, knowledgeable and went above and beyond to make sure we were happy. I'm only giving 5 stars because Danny was extremely helpful and had no problem getting our issue resolved. I would've given a lower rating after our horrible experience with Josh which almost caused us to completely take our business elsewhere. Thank you to Danny for being wonderful and helping us and for being the only reason we chose to stay! ... Read more

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.
