Area safety: I was unsure about spanish harlem at first, but in hindsight it's just fine. Got home around midnight by myself and felt very safe. There's a 24h car wash just opposite the house which means it's never completely dark outside. Still, it's not the place where you want to flash your latest iphone around too much!
Hospitality: great, Bia was there to welcome me and she gave me several tips. I wish I had more time to hang out with her.
Room: a bit oldish, but spacious and clean. It also has a big tv with HBO and stuff in case you want to stay in.
Comfort: ok, but you may want to bring some earplugs. The noise from the other flats in the building and the 24h operating car wash just outside the room window did challenge my sleep!
