My in-laws stayed from out of town for a two month stay as they were helping my wife and I with a newborn. At the end of the stay the host tried to charge an extra cleaning fee claiming an 'extreme buildup' on one floor and having to throw out a bathmat. What was shown was anything but an extremely dirty floor. The host also claimed they failed to keep the minimum amount of care yet they purchased their own cleaning supplies which they also left at the apartment. The place is old and the host was claiming that it was spotless when it was anything but. Please make sure you verify and take pictures of the condition of everything before the host tries to make a claim on you after your stay.
The weather turned cold one day also and the heat was not working so the place was freezing. It took over 10 hours to turn on. I imagine this would be problematic in the winter months in NYC.
