We were welcomed by Gregory, who is Irina's housemate. Gregory is a very nice man and we didn't see Irina much.
The location of the appartment is very good, because many things are on walking distance. If you are lucky you can park your car in front of the appartment. Pay attention to the street sweeping hours, because during these hours parking is not allowed.
The appartment itself needs to get a proper cleaning, because it is just nasty in our standards. The room has dust everywhere and there is mold/fungish on the bedroom walls. The room looks as if there hasn't been cleaned for a long time.
The bathroom down the hall was ok, but not clean as well.
We would look further and pay more for a cleaner place the next time we visit San Francisco.
