We went here with as a family with three young-adults (18+). We got a larger suite which was perfect. Two double-bed bedrooms, bathroom with bath/shower and a sofa-bed. Flat screens in both bedrooms and in the living room. A six-chair seating area and two large sofas. More than enough space for 5 adults. A kitchen with cooker, oven and fridge (we never used it however). Air conditioning in the bedrooms and living room.
We spent little time inside though and exploited the opportunity to explore the city. It is really nearby metro stations and the city has enough to offer to keep you occupied for weeks I'd say. We were only there for two full days, but we hardly spent time in our suite. The staff was really friendly and helped us arrange transportation to the airport.
Only downside: the breakfast room is really small and we were forced to have breakfast outdoors once because there weren't any seats available. There's a nice bar on the corner of 51th and Lexington, called Cafe Metro, that serves a wide range of breakfast dishes.
