The host of the AirBnb we had originally booked canceled our reservation at the last minute, so we are very grateful to Sophia and Duda for rescuing us and accepting our reservation request on the same day! They have been very kind and responsive, and they also allowed us to check in early, as soon as we arrived in the city. The apartment is well located, right next to Columbia University and Morningside Park. We found it very clean. The room had air conditioning and the apartment had everything we needed, including well-functioning Wi-Fi.
