A friend and I spent a week in Daniel's apartment last april.
His flat has a perfect location (bars, restaurants, metro, cool areas of Manhattan and Williamsburg...) Also... the rooftop of the building is perfect for having a drink after a long day in the city.
Daniel has been really helpful during our entire holidays, giving us great tips and advices, more generally, he did everything to make easy our trip in the city.

I would definitely recommend the apartment to everybody who wants to stay in New York for a few days or even longer.
