I had read some reviews about the check in process being cold and impersonal... My experience was just the opposite. Evone checked us in and could not have been nicer or more helpful. In fact the all of the check in staff seemed very helpful. Just ask for what you would like and they go the extra mile to accommodate. Our room is nice and a good size for a family of four.

I stayed here for one night from 12/26-12/27. The hotel is right next to Grand Central Station which, of course, is very convenient. However, it makes it very busy and loud. You get noise from people and noise from honking vehicles and sirens from emergency vehicles. The woman who checked us in was nice and gave us a king room, 3012. The rooms, by NYC standards, are good size. The design of the rooms are modern and ugly in my opinion. There's a huge wall size mural on the back of the bed and the room is painted an ugly pewter color. The carpet is black with small pinstripes. If you like modern design then maybe you won't mind. There's an ironing board and hairdryer but no luggage stand or coffee maker. I am seeing less and less coffee makers in NYC hotel rooms, very disapointing. The bed was comfortable but had 3 postage stamp sized pillows. For a king bed you need larger pillows and more of them. The bathroom was average size but had a small sink with a shelf above it that I almost hit my head on when I bent down to wash my face. There was also toothpaste splatter all over the wall next to the sink (gross) which I ended up cleaning. The toilet is an industrial type with a loud flush. It was ugly, loud and didn't even flush properly. There are plenty of 4 star hotels in NYC, I would choose another one next time.

I've stayed at Grand Hyatt in June 2012 and this hotel is great. Its location is priceless having a private access to Grand Central.
Everything looks pretty new (not sure when it was reformed) - the room was perfect, the lobby and receptions are great not to mention the staff which was really helpful and educated.
Check-in/check-out were fast and without surprises.
Did not have a chance to check other services like swimming, Gym etc (not even sure what they have).
