We spent 6 days at Xiren's cosy apartment as a base for an exploration of New York. It was exactly what we needed! The apartment is located in a great neighbourhood, we felt that we could have easily spent the 6 days just exploring the diversity of restaurants, bars and shops around us. Also, we never felt unsafe walking home. It's a little walk (some 10 mins) to the nearest subway station (F line) and from there we had easy access to all of Manhattan. Whereas the neighbourhood is rather busy (particularly on a Friday night), the apartment is surprisingly quiet, as it's on the 5th floor and the windows face the back of the building. We could hear steps from the neighbour sometimes and the radiators made a few noises at some point - but nothing to bothersome and otherwise the building was really calm.
The apartment was lovely, exactly as charming as represented in the photos. The bed was comfortable, the pillows too. The kitchen is a bit basic but it had all we needed to prepare light meals at home.
Xiren was an excellent host, responding promptly to any communication and giving us flexibility with the check-in hours. She also provided precious advice of good restaurants and other places in the neighbourhood.
In summary then, I strongly recommend this apartment, and would not hesitate to contact Xiren if I ever find myself in New York again.
