It's a small room and you can indeed hear the train quite clearly, but it didn't bother me at all, as I was just there for the night. The kitchen is big, the bathroom is very nice as well, great location, well connected to both the airport and Midtown Manhattan. There is a nice supermarket nearby and a copyshop for you to print the boarding pass ;) Even if I would come back late at night, I felt safely in the area. I didn't meet Nia, but she replied quickly when I asked her a question. A very good value for money!
