Like others already wrote, this is a hotel-like accomodation. We booked #714 but got #710 instead - the rooms are shuffled around, but all of them should be the same. The room is simple but clean, must have been renovated recently (the view from the window was not that nice - just a wall of the neighbor building, but whatever, I used the room just to sleep and wash). The bathroom was fine, there were shampoo and soap dispensers, towels were clean (my girlfriend, which is extremely careful about cleanness didn't hesitate to use them). Heating is provided by a small radiator, but don't be fooled, it can get the room really too warm. The water in the radiator made some noise when open too much, so we let the room warm during the day and then turned it off for the night. The hotel also has a kitchen (without fridge) and lounge, but we did not use those. There is a free wifi, but seems with lots of guests it becomes a bit slow at times.
The location is perfect... You are really in the centre of San Francisco, great for walking around. It can get really loud in the night (especially during weekends), so bring earplugs if you're bothered.
All in all really good value in SF, where hotels are really expensive if in a good location (but our friends stayed in an expensive hotel on the Nob Hill and they still heard lots of noise in the night and had to walk uphill/use tram/uber every evening, Bunkhouse better placed)
