We rented Krzysztof's apartment for my parents, the apartment has a good layout and is pretty spacious, especially the bathroom (for NY standards anyway!). Krzysztof is very responsive and accommodated our requests quickly. The heating system is a little bit dated and can get pretty noisy. The apartment has a convenient location, however, the traffic from the BQE (highway) is pretty heavy and you can definitely hear it from inside the apartment. Overall, we had a good stay!
