First of all Sylvia is a great host, always available to answer to your doubts, give you tips, and helping you to have the best nyc experience.
This apartment is perfect to visit NYC. It is literally 5 min walking to the subway and next to supermarkets and other stores.
The subway lines take you everywhere in the centre directely so is perfect to visit the city at any time of the day and return to rest in a safe, calm neighbourhood.
The house is fully equipped. The kitchen has everything to cook good meals (although the healthy supermarket at the end of the street has great take away options).
The area and appartment building is extremelly calm and safe.
The only small downsize for me personally was the matrisse, that I didn't find to be very comfortable for my back, but it is a personal opinion.
