We had a fantastic 9 night stay in the apartment. It was very clean, quiet (very unique for NYC!), spacious and comfortable for us (4 adults and 1 child). Dirk and his family were so welcoming and helpful throughout the stay: there was a delicious welcome cake, assisting my parents with their bags and arrival, a well equipped apartment (kitchen has everything you need, and Dirk kindly provided a box of toys which kept our daughter happy for hours and a stroller for us to all get out and about despite the jet lag) and farm fresh eggs from the farmers' market. We valued their local knowledge and assistance, especially when our daughter broke her arm...the advice helped us get everything sorted very quickly. And the garden is a little oasis.
All in all, I can highly recommend Dirk as a host and his apartment. We had an excellent experience and would definitely return.
