They reel you in with cheap online prices, a couple months later they’ll double if not triple prices without warning. This location in particular has constant door issues whether they’re stuck open or wont open as well as the main gates too. The issue with the doors being stuck open is they knowingly have a rodent issue since their is a bus station built next them that shoved a lot of the areas wildlife into the place. Our unit was unfortunately victim to rodents.
