Wish we could have stayed longer!
We got a timeshare exchange week at the Manhattan Club and were very happy with our stay. After a week was up, we shifted to another hotel for 4 nights near Soho. But wished we could have stayed all 11 nights at the Manhattan Club. 
I'd been apprehensive about some of the reviews I'd read about the Manhattan Club earlier, but we didn't face any such problems. We didn't have anything but normal waits for the elevators, though the doors tended to shut a little quickly. On one occasion my little kids stepped out of the lift, but I couldn't before the doors shut. They were a little scared till I managed to ride back up to meet them. 
We were on the 23rd floor looking out onto Carnegie Hall. The one-bedroom suite with kitchenette, dining table and 2 bathrooms was spacious, comfortable and well-maintained. Housekeeping was excellent. One minor irritant was the mixer in the showers. The water was either too hot or too cold... at the right temperature it would be a trickle!
The marketing department called, asking to schedule a presentation visit. But I declined and we received no more calls after that. 
The staff were friendly and helpful, with subway directions, suggestions and receiving packages. On one occasion we needed a screwdriver to open a new toy my kids had bought. The staff helped out. 
We really like the location close to Central Park. We could walk to several places and the subway connectivity was good to get to places further afield. 
There were plenty of stores nearby to pick up snacks for late-night hunger pangs. And my husband often brought back some take-away, as the children would be too tired to go out for dinner after being out all day in the city. The dining table made it comfortable to eat in. We would get breakfast at Fluffy's Cafe and Hello Deli nearby. We didn't try the breakfast served at the hotel. 
We had a really lovely stay. And would be happy to stay there again.
