I was very gratefull for how nice and how well they worked with me getting my stuff stored. However, it would be nice if storage companies would go back to being just storage companies instead of being money hungry. There used to be a time where you could store your stuff and not worry about it. Now, they insist upon raising rent and letting you know that it's supposed to be temporary. Which really makes no sense whatsoever. You make money off the storage of every unit. There is literally no issue with someone storing their stuff when you make money every month. Make it make sense. ... Read more

This particular storage facility provides self storage units of different sizes, ranging from 20 to 400 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.

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.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items.
