I choose this apartment because of its great reviews, so now is my turn to contribute with mine.
The location is perfect! between 5th and 6th Av. and 3 short blocks to Central Park.There is a grocery store just around the corner and many subway lines nearby.
The apartment was very clean and it has everything you need plus small things like extra sheets and blankets, towels, hair dryer and even soap bars. Also having a washer and a dryer is always very useful.
Kurt (Jon) is a very nice and helpful host, we had an issue with the oven (totally our fault) and he solved it with promptness.
I would be very happy to go back to this apartment. Highly recommended!
