Karen's apartment was a great place to stay for our New York visit. The apparent was just as described and very clean. There were a lot of house rules, and we were always a little afraid that we broke some of them, and the internet was more off than on, apart from that we enjoyed our stay very much.
We really liked the neighborhood, and with Karen's maps and suggestions to where we could go for groceries and food, it was no problem to find the good spots in a neighborhood that we probably would not have visited if we were not staying there. We felt really safe in the neighborhood.
