We spent a wonderful time at Jay's apartment.
It was clean, nice and close to the Q subway which takes you to the very center of Manhattan.
Jay was welcoming and helped us to carry our luggage to the 4th floor. He took the time to explain us how everything works. He answered quickly to our questions when we had texted him. He was discreet but very helpful.
In a word, It was GREAT to stay there ;)
