My stay at Landmark's 250 Taylor St. location was okay. I stayed for a month and a half, originally planning on staying for a month, and they were very accommodating and extending my stay was easy. The room itself is fine, nothing special but overall it was about what I expected.
The hallways and lobby are pretty dirty, with some bad smells as well. The laundry room was pretty run down, but it got the job done (if you were able to secure one of the 2 washers). My main problem with the stay was the location. Yes, as Landmark says on reviews, homelessness is a problem all over SF, but it should be made clear that this is in one of the worst possible locations. The building is in the Tenderloin and is right next to a church that presumably offers out reach to the homeless. It is very loud and I was uncomfortable a couple of times with people screaming at me while walking home.
Overall it was a decent spot and the room itself served me well. Only downside is the cleanliness of common areas and the location.
