Our stay in this appartment was Totally to our satisfaction. It was like the whole appartment belonged only us. Just in the Morning we saw some other guests but the appartment was big enough so the guests don't disturb eachother.
The next train Station is a 10-Minutes Walk away so one could get to the nyc spots in 20-30 minutes.
All Common Rooms Are always clean and one's private room too.
I have only one Suggestion: there should be a mirror in the bedrooms too.
