We stayed at Aaron and Alissa's place in Harlem for almost two months. We had a wonderful experience. The hosts were kind and helpful. When anything did not function (or we did not know how to operate) in the apartment, they were immediately available and very generous in their help. We felt welcome very welcome. The location is great, next to public transport, whole foods, nice restaurants, and a 15 min walk to Morningside Park which is wonderful for kids, and a 25min commute to Columbia campus, which is a very pleasant walk in the morning. With the express A right there, it is super easy to get to and from the city center very fast. I really recommend their place for a long stay in Manhattan!
