The staff is very nice but the building is very confusing and inaccessible.

Its a very decent YMCA all the staff are very kind, very approachable. Everything is on-line like schedules and classes makes it super easy to sign up. A bit more expensive than a regular gym so to get your money's worth definetly use the pool. You will be paying way to much if you go as a guest so definetly get a basic membership and add what you need to that. I went because it was very close to me on Mass Ave in Cambridge across from City Hall. Definetly worth a look! A half block from the 1 Bus and 2 blocks from the Central Square Red Line T Stop. Walk up Mass Ave and when you pass the large post office building you're almost there. Kind of easy to miss the YMCA the first time. Also there's a ramp entrance on the side. I was pleasantly surprised how nice they are at the YMCA
