It's a good stay for 3-4 people max. The best part is probably that there are two bathrooms - that is certainly what made me stay here and also because it's good for its value. The host is very responsive and the location is not too far from Manhattan - maybe 30-45 mins train ride.
I would just say you will naturally hear foot steps and noises coming from upstairs at any hours of the night since people live there of course.
