Our room did not have an own shower and toilet, but it is straight on the floor and we had no problem to take a shower or go on the toilet.
It was quite noise during the day as well as the whole night, but it never prevented us from falling asleep or feeling uncomfortable. On the contrary, I felt that all of the described made me feel to be in the real "San Francisco scene", it was enjoyable!
Due to the many negative references, we arrived at this place with a horrified expectation of a very bad place and were positively surprised.
First of all, about the location, that everyone complains so much about: The location is great, it is so central to the Downtown area, shopping mall, Market Street, many major attractions, the central train station and the Streetcar as well as the Cablecar network. You can walk to all of the above mentioned as well take the Cablecar or Streetcar to Fisherman's Wharf and so much more.
Yes, the street itself is not the richest, but I wouldn't call it Ghetto either. If you have ever been to a real Ghetto you will agree with me that this is not a Ghetto. And as some people mentioned: San Francisco is dirty and ugly in a lot of places anyway and the "rich" and "poor" streets are next to each other, so it doesn't really matter and I never felt unsaved or have been harassed, attacked or robbet by someone during our stay. Even at night I would dare to get out and come back because there is police all around Downtown and the people on this street only mind their own business. Someone once told me: If you see a lot of homeless people in an area you can be sure that this area is safe, because homeless people would never stay somewhere where it is not safe or violence happens, because they are the first victims of both.
About the drug dealing: I never saw any drug dealing and yes you definitely smell weed all day and night, but then again: You do so everywhere in San Franco, it doesn't matter where you are. This city is smelly and dirty just wherever you are.
The Motel / Hostel is definitely not very nice, but not that bad either. The room was perfectly fine, yet it was not as clean as a Hotel might would have been, but also not dirty.
The WiFi, which was included, might not have been the fastest and did work during some busy hours, however most of the time it was fast enough.
