Isabel was on site and took the time to explain all the details of the apartment. The apartment is 5 minutes from the Ralph Ave C station and has a separate entrance.
There are plenty of sleep options; one full bed, one bunk bed, and a pull-out sofa. The apartment has been furnished with much forethought what travelers might need - lots of maps, toys for kids, wifi, hair dryer, beautifully renovated kitchen. It was clear that this was not a hastily cobbled together residence.
Isabel is very friendly and if we had had any issued I'm sure would have been very responsive.
The only caveat I would have is that you do hear everything going on in the floor above, which made naptime for my toddler a bit tricky. But that is a minor, very minor point. I wholeheartedly recommend this place for your next NYC trip!
