Great experience, stayed a couple of weeks in July with my wife and three months old baby. Loved the private terrace (nice view!) and location not far from Central Park and Midtown.
Lindsay was a great host, arranged everything we needed, from bath amenities, towels, extra clothes hangers, coffee and sheets. Communication was easy, texted most of the times. There's a laundry room in the basement but we dry cleaned all our clothes.
The building is well maintained, with a good working elevator and air-conditioning. The apartment is not big but more than spacious enough to accommodate 2 or 3 people. What we loved most was the fact that it was a duplex, so it felt more like a house with separate rooms. Would definitely recommend to stay.
