Great Location - Friendly Service
First of all, access from JFK is very busy. Just take the airport bus to Penn Station, and it is just a short walk to the hotel. Due to my Hilton status they upgraded me to a higher floor, and service at check-in was very friendly. The internet in my room was both fast and free.
There were a few black hairs on one of the towels in the bathroom, and the ventilation fan in the bathroom was also extremely dirty (probably has not been vacuumed in years). Other than that the room was excellent, though small.
Finally, just a general complaint about in-room dining in hotels. In addition to the prices listed in the menu, the DoubleTree Hotel will charge "a dining charge of $3, a 3% administration fee, and applicable taxes". In addition to that, you have to tip the person bringing you the fee. Why not simply have an all inclusive fee? They make it so complicated sometimes.
