Being a new yorker, I am very familiar with this sort of housing. In NYC we call it a single residence occupancy hotel. The building is over 100 years old and was built as a medium to long term hotel originally. There are some tenants who are long-term (decades, even) and some that are just overnight. My room had a bathroom in it, but the presence of hallway shower and toilet rooms speaks to the fact that some do not. This is typical of SRO-type housing. The building itself is very nice - first floor coffee and washing machines, and the room was clean if a bit spare. My only real complaints were small ones - WIFI is a bit weak, and the bed was on rollers. Given that the building is so old it shouldn't be a surprise that the floors are a little uneven, so the bed would roll away from the wall. A quibble, but it would be nice to have locks on the bed wheels. Location can't be beat - walking distance to Chinatown and major Market Street public transportation including the BART.
