The apartment is very clean but we found it very sparingly furnished (there was one sofa only - although there were dining chairs, we felt these were uncomfortable to sit in after a long day spent in Manhattan. We did mention this to the host and I hope that he does add 2 armchairs as this would allow family/friends to sit in the evening and chat about their day in the city).
We had a few issues with missing items (cutlery), which were quickly replaced by the host which was wonderful. Only additional thing I would add is that cloth-dryers would be good to dry wet towels after showers and if these were replaced - as a routine - after 3 days.
It was very noisy in the late evening/early morning - dogs barking without stop and garbage trucks which if you live in a city, might not be that annoying but we live in a very rural area and so we were disturbed most nights.
The subway is only - as advised - 8-10 minutes walk away, but the train to Manhattan often took around 30-40 minutes.
