Our stay in Greg's Apartment was great. We were 3 and the stay was very confortable. On arrival we met with Stewart (Greg's son) briefly to give us the keys, show us the apartment, and provide us with more fresh towels.
The apartment was cozy, tidy and clean (no excellent cleaned but OK). Due to we stayed for 8 nights, we missed to find at least a bar of soap and more toilet paper (only 2 rolls), but it wasn't a problem because there are a lot of groceries closed to the apartment.
The kitchen is really small but it has everything you would need. We used it 4 or 5 times and it helps to save some money.
The main room is big, with a big and confortable couch, satellite TV (about 40 inches), and natural light through the windows facing the private garden.
The bedroom is suitable for 2, the bed was very confortable. It has also a Satellite TV, a wardrobe, and a furniture with drawers. The windows are facing the 69th street. It's a quiet street, but you could hear cars, trucks or even people if they are crossing the street because windows are old and its don't provide great protection against noise. Wardrobe and drawers allow to arrange your clothes conveniently if you are 2, but if you are 3 the space is a bit tight.

Anyway, our stay was really great and we enjoy the apartment and we consider a great value of money. The situation is very good, closed to shops and groceries (food emporium), 3 blocks to Metro, 4 blocks to Maddison Avenue and 5 blocks to Central Park (5th ave). Surely, we would repeat our stay.

The only real problem we had, is the sofa in the main room is not a sofa bed, it's only a big-confortable sofa, but not a sofa-bed, so we don't consider suitable to be used to sleep. This is the only reason because we mark 4/5 stars instead of 5/5.
