I'm a junior professor at Baruch College, New York City, where I teach Philosophy. I am also completing my PhD at the CUNY Graduate Center. I'm originally from England, and I moved to New York for my studies.
David's points are mostly fair, and I wouldn't raise a major issue with any of them. I would like to stress, though, that the apartment is thoroughly cleaned for 2 hours by professionals booked via Airbnb before each guest arrives (in addition to a set of clean sheets and linens). Drapes are washed every few months, but I will make sure this happens more regularly from now on.
The apartment *is* a rental and is in an older building, and my lease prevents me from undertaking any major refurbishment (plastering, painting, etc.), though it is due for some refurbishment in 2015. But as David also notes, the apartment is in an incredible neighborhood, and about as central as you can get for tourism purposes. If you are looking for luxury, then you might look elsewhere (and be prepared to pay MUCH more!), but if you're looking for a great base in the heart of the city with privacy and the all necessary amenities, at the fraction of the price of a hotel, I don't think you can find a better deal in New York!
