Convient hours, safe, quiet. They have little attic units above their regular units that are accessable using rolling stairs and they're pretty neat. You just have to be able to lift everything above your waist to get stuff into the attic units. If you can get a unit on sale it can be a great deal.

DO NOT RENT FROM EXTRA SPACE. Never any carts to help move things, staff are very rude and disrespectful, parking lot has giant potholes that will mess up your car, elevator is always broken and you can’t even use the stairs to get into your unit when the elevator is down because they are all locked. Most of all, the prices will raise $100+ will little to no notice. I wish I never rented here it has been a nightmare

The customer service was very helpful and very, very friendly. I recommend anybody who needs their assistance to come this way. Just a customer service loan was 1 foot in the door. It was excellent.
