Saya and Diego were the best hosts I could hope for, they have two lovely children and they are very helpful. As a matter of fact, they even invited us to join them for a barbecue at their place my first weekend there. They know New York really well and can provide a lot of helpful informations about the city for your visit.
As for the flat, it is as showed in the pictures, really clean, really big. The subway is really close by and accessible.
The flat is a great place to stay when visiting New York because of its location and its owners.
I will surely go back to their place if coming back to visit New York.
