It started off as a good experience initially. Then they limited the hours I can access my unit, and the price went wayyy up. To the point where it’s completely unaffordable now and I have to close my account with them.
Sarah, we apologize for the frustration with rising costs and limited access hours. Please call us at (603) 696-4422 to discuss your options.

I wish I could give zero stars. Extra space storage does NOT like to respond to people when ot comes to their storage being Auction off. I was told my personal family pictures as well as ALL my papers that were inside with my pictures would be returned. I never received a phone call from them in regards to my items. I had to call them repeatedly until I got through to the RUDEST woman on the other end of the phone telling me my personal items NEVER was returned. I will be in search of a lawyer because if my personal information is used Extra space storage will pay for it.
