I stayed 2 days at Sarah's and this was my first time in a shared AirBnB space. The apartment was just as described. It is a good place for someone spending most of the time roaming around the city and just needing a place to sleep. Two rooms in the apartment are used for hosting, but my room could be locked from the inside while I was in, so I felt safe. Sarah seems to be judicious about whom she hosts, and kept me in the loop are about the check-ins/-outs in the other room. I used the kitchen, which was spotless, to make a microwaved dinner. The bathroom was also clean.
The only downside to the stay was that the neighborhood didn't feel quite safe for me to walk alone at night, mostly because there were some struggling people, fairly intoxicated, asking for money on the street and the entrances to the subway. Luckily, the area is busy enough to alleviate some discomfort. Sarah herself was friendly and kind and I am glad I got to meet her and have a chat with her!
