Despite the bad fame of this place, I personally (as a solo female traveler) didn't feel unsafe even for a second. To be honest, I liked the neighborhood. Almost every day I came back past 11pm and no strangers bothered me, everyone was nice and helpful, so I don't know... I don't complain about the location.
The room itself was nice. Cozy, with a comfy bed and a lot of tools to organize your things. The only detail that made me a little bit annoyed was the construction work that was happening through at least three days right next to my window, which I couldn't close due to the AC machine. Maybe it's good? Otherwise I wouldn't like to leave that perfect bedroom...
Some places are shared, but I never saw other guests. Host was kind and hospitable and I also made a friend from the next door (the only guest I actually saw) with who I spent some crazy days in NYC.
To sum up - I highly recommend Fazia's place. Close to the shops, subway or buses, very well air-conditioned.
