Kevin was a wonderful host. He welcomed me when I arrived at the apartment and was available to answer any questions I had throughout the visit. (It helped that he lives in the building.) The apartment location was incredibly convenient to a conference I attended near Columbia University and to the Subway. The sleeping space is below ground, so though the winding stairs took some getting used to, I slept like a baby in the quiet bedroom. Wifi was slow, but who wants to stay home all day and sit on the internet anyway? I would definitely recommend staying here.
