This place is beyond unacceptable. I’m honestly shocked it’s allowed to operate. Mold is everywhere, the stench is unbearable, and it feels downright dangerous—like stepping into a horror scene. The polished photos are a lie. This place should be condemned. It’s unsafe and terrifying, and frankly, it’s appalling that it’s still running…

I had the worst experience with the Extra Space Storage at 37 River St Waltham MA .I went here to rent a unit for a week while I waited for my new apartment to be renovated I spoke with the guy and told him I would like something on the first floor because I knew it was going to be a fast in and out as my new apartment was a week away from being ready .The guy then informed me that they only did monthly rentals and also didn't have any open first floor units "but don't worry We have elevators" so I said ok so they rented me a unit on the 3rd floor saying I would have access to the elevators . I rented the unit came back the next day to move the stuff in and the Elevators now had a out of order sign on them I went in the office to ask the guy when will they be fixed and he said he didn't know but I could "use the stairs ,the elevator is a luxury" 🤬I then replied telling him the only reason I agreed to rent that unit was because of the elevator that he sold me on he then replied with the same "use the stairs ,the elevator is a luxury". Went back to the office and was told this is a walk up unit.
