We stayed for 5 nights at Daniel's apartment in mid December. We had a great stay. The location is fantastic, easy walking to everything in Midtown (or further depending on how energetic you are), and within 5 blocks of both Grand Central Terminal and 51st St subway for access to the 6 train. The apartment was very clean and comfortable, the kitchen was small but well stocked, wifi worked well. It was nice and quiet on the 11th floor and was secure with a doorman. We would definitely stay here again.
