I stayed there with three friends for three days and it was really great. Nice and tidy room but a bit small for four persons. That was not a problem for us since we only stayed there to sleep. Ben was really friendly and gave us many recommendations for bars, restaurants and anything else which were all great. The location is perfect. The subway is nearby so you can reach anything and good restaurants are very close.
We had a great stay in New York City. I would definitely recommend him as a host.
