First of all the place is just as it looks in the pictures and descriptions. It's super clean, really quiet, very close from both subway station (literally 5 min walking slow). Access to Manhattan is really easy, less than 15/20mn all in all. Flat is also very accessible for elderly people (my 76 and 80 years old parents I'm our case).
William really took care of us and of took very seriously any of our request
Definitely to recommend for four people.
