We stayed for a week during Christmas break with my family of 4. The apartment was perfectly clean and exactly as advertised. The location is really convenient, ten minutes walk from the subway that will take you to Manhattan in no time.
Jeffrey is a very reactive and attentive host who gave us all the necessary informations for us to enjoy our stay and even more (we specially enjoyed the chocolate cookies).
Conclusion: We recommend Jeffrey's apartment without hesitation and will stay here again when going to NY.
