We had a nice stay at Olga's place. Yes, the place is close to Central park, but It's very close to Harlem, which felt a bit dangerous when returning back to the Air bnb at night. Pilows were a bit too flat, making it hard for a good sleep.
Shared bathroom is clean, and the room is also clean.
Check in was super easy, Olga's daughter just buzzed us in and gave us keys afterwards. There's a AC unit in the room, so it was nice and comfortable for our stay in September. They do have a small dog and a cat, so make sure you aren't allergic.
