Karen is a very nice lady and she really wants your stay at her place to be a good one. Her apartment and bathroom are very clean. The room I stayed in was also very clean and neat as well. As several reviewers mentioned, her apartment is conveniently located/very close to a train station (walking time about 2 minutes with short train rides and easy access to Manhattan) and the neighborhood appears to be very safe. Some reviewers mentioned some noise from passing trains because of her close proximity to the train station, but I found the noise to be a minimal issue that was tolerable and did not effect my sleep at all. Overall, I would recommend Karen and her apartment as a good choice if you are visiting NYC and if you are searching for a nice, friendly host, a very clean place and easy access to public transportation.
