Anne's place is in a very good location, close to the subway and everything you might need during your stay. There is a very small kitchen that you can use if you get tired of eating out or prepare snacks for the day.
It didn't feel as if Anne made special preparations for our arrival, and in particular the bathroom was not clean. Not extremely dirty, but we didn't feel comfortable using it before cleaning it ourselves. The rest of the apartment was also a bit dusty.
Anne was fair enough and reimbursed us, and perhaps it was a one time problem.
There is central heating in the apartment, and it works very well when the landlord turns it on.
All in all we stayed 8 nights and enjoyed our time in NYC, but would look for another place if we get there again.
