I'll start with the bad aspects. The flat was not very clean when we arrived. There was a bit of dust on the floor. The carpets in the bathroom were VERY DIRTY (even though Dil offered to reimburse us if we wanted to buy new ones). The dishes in the dishwasher were not clean, and there was no dishwashing liquid to do the dishes by hand. There was indeed a hairdryer, but it was actually a heating brush that was FULL OF HAIR. This was disgusting, and I had to buy a new one. In addition, the shades were broken, therefore letting the light through very early in the morning.
Also, Dil could have been more responsive and helpful. I got no response when I asked what to do for the shades.
On a more positive note, the flat is very cozy. The view is amazing. The building is secure and the area is in my opinion the best one in NYC. Plenty of restaurants nearby. Metro station at >10mn by walk. Very central.
