I had a wonderful stay at Nayoung's place! Cozy and clean in a safe neighborhood about 3 blocks from the 7 train stop. The apartment was very close to the train lines, but the train noise didn't really bother me and the neighborhood was quiet other than that.
Nayoung was out of town while I was there but her friend took excellent care of me and shared advice and tips for things to do in the city. It was my first time visiting NYC and I couldn't have asked for a more wonderful experience!
