Ignore the naysayers
We booked this quite a long while ago - but as I occasionally checked TripAdvisor, I saw a fair number of negative comments and was concerned as to whether we'd done the right thing.
For sure we had - a great property - lovely spacious room - had a half price upgrade to Grand Club - and that was tremendous - lovely healthy breakfast - and the wonderful Club Terrace - an oasis of peace and calm in the madness of Manhattan.
Used the Market most nights - very useful facility.
Loved our visit to Grand Hyatt on 42nd St - a really central location - could walk everywhere.
