Gregory was really helpful even before we arrived, providing us with all the information needed. On arrival we were shown around the flat by Gregory's son. The flat itself is on the ground floor of a lovely brown stone in a quiet area on the Upper East side, with the metro and a supermarket close by. The flat is spacious and comfortable furnished, and has access to a lovely private garden (which was handy as temperatures soared to 30 degrees during our stay). It was a great place to come back to after spending a day exploring New York.
