Jennifer was a great host !
Firstly, despite we were late (roadworks), she was waiting for us and did everything to make us feel immediatly good.
She was always avalaible and happy to answer to my questions (despite my low english skills) and she would be glad to help you discover the city, especially Harlem.
The apartment was really clean and big enough to welcome all of us (5). It is also very well-located and it's not far away from the south of Manhattan and all the "touristic" places.
It was so a very great experience !
