First we were kind of sceptical whether it was the right choice to stay in Brooklyn. However, we can really recommend it. Ana's and William's house is ~7 min away from the subway and when you buy a 7-days-subway-ticket for 31 dollars, it's a quite comfortable (and cheap!) way to discover New York City. (You definitely must check out the Brooklyn Heights at night!)
The room itself is very nice and large. We had everything we needed and we loved the special atmosphere in there. Only two minor critical points: The toilet wasn't working that well and the heater was making loud noises at night. However, you just have to turn it off at night and everything will be fine. Allthough we didn't have a lot of contact with Ana and William, they are very kind and funny persons! A really recommendable and affordable way of visiting NYC! :-)
