I (from Switzerland) was visiting New York with my 15 year old teenager daughter. We used the place mainly just to sleep and for that it was okay. Nothing exceptional, but okay value for money. We were warned by local friends that the area is dangerous, but felt safe walking in and out of Harlem to the city as well as by tube at all times and had a really good time in NYC.
Took a while to get the Wlan going due to a wrong password on the webpage, which should be corrected.
Had no contact with the landlord, but chech-in and check-out worked well with key in the safe outside of the house.
