The apartment is very nice compared to NYC standards! Pictures are very representative.
The position is excellent: 3 min walking from the subway and 8 min walking from Union Square. The neighbourhood is cool, very quiet and amazing for going out for dinner and drink, walking distance from many restaurants and bars.
Kat is a super nice host, she gave us all the instructions to reach the apartment and to do the self check-in, also recommends on amazing restaurants both in the east village and in China town.
Highly recommended.
