Booked our stay thru Priceline, so had no choice on hotels. Just wanted to be sure we got at least a four star, to make sure our trip was enjoyable and as problem free as possible. The price was ok, I've seen higher and lower prices for the same hotel, so no complaint’s there. What I can complain about was the cleanliness of our rooms and the noise. The room itself was sized well enough but the bathroom was not. It is way too small. I’m 5’7” /140lbs and found it a bit annoying to move around. There is little to no space to put your bathroom essentials and there’s a considerable amount of mold and mildew in the shower and on the ceiling above the door. Apparently the housekeeping staff isn’t trained in correctly cleaning bathrooms which is evident by the abundance of dried urine around the toilet. Come on now people, everyone should know how to clean a bathroom, especially if you’re getting paid to do it! No ventilation fan, so you might want to shower with the door open, but that leaves you with a host of other problems doesn’t it. The Grand Hyatt creates the illusion of a larger room by doing away with furniture. The window ledge acts as a table for the ice bucket and glasses. Feel free to call and request a mini-fridge at $25.00 a night, if your phone works which ours didn’t, along with several light bulbs, oh the list could go on and on…Let’s review:
•Extremely small bathroom
•No ventilation fan in bathroom
•Mold and mildew abundant
•Dried urine around toilet and on wall
•Broken room phone
•Lack of space to put your things
•Several burnt out light bulbs
•Dirty sheets (what surprised?)
•Mini-fridge for $25.00 per night based on availability
•Thin walls, Mr. and Mrs. Next door discussed in depth their itinerary for the weekend and upstairs seemed to be practicing for a demolition derby
•Location was ok, but if your staying anywhere in Midtown Manhattan – your close to everything, period.

The hotel staff was courteous but was not about to go out of their way to be helpful.
Not what most people would expect from a four star hotel. Lesson learned: you get what you pay for. Next time, I’ll go with the TripAdvisor Hotel Rating, before buying.

I live in NYC, but wanted a quick getaway from my apartment, so decided to spend a night at the Grand Hyatt. I booked the room through priceline, so did not actually choose the grand hyatt, and after reading reviews, I was expecting a less than perfect evening.

Fortunately, I was pleasantly surprised! The room was spotless, and not exceedingly small by NYC standards. The bed was so comfortable and the sheets and towels were clean and smelled freshly washed. Service was prompt and courteous.

My only complaint is that the walls are thin, and I could hear conversations of our next door neighbors. Thankfully, they were not around much. Perhaps reviewers are not used to the limited space that New Yorkers are used to living with. Yes, the rooms are small relative to what you would find elsewhere, but that's to be expected here. Also, room service is so expensive, and there are far too many delicious and relatively cheap restaurants in the area for anyone to order room service. I actually ordered food from a nearby restaurant to be delivered to my room and had no problems.

I had a wonderful stay and would recommend the hotel to anyone.

Ok, The only positive things were the location and the lobby. But the rest of the hotel was the worst I've ever been in New York. This was my third time visiting New York but the first time staying at the Hyatt. I thought I was getting a 4-star hotel but it was more like 1.5 to 2. The problems were, but not limited to, small room, very small bathroom, very thin walls (could hear our neighbor sneeze and snoring), the towels were OLD and smelled horrible like they washed them in plain water with no detergent, the internet was not free, there was no refrigerator in the room (strange); the staff was not very pleasant (not much on customer service), and the elevators were super slow!

Overall, I liked the hotel. But there were definite pros and cons.

Pros:
Great location. Adjacent to Grand Central Terminal (Station). You don't even have to walk outside to get to the hotel.
Nicely designed and decorated.
The fountains in the foyer have a calming effect.

Cons:
I paid rack rate, and ended up in a tiny room the first night. I asked for and received a much nicer room the next night. But I was disappointed with the room assignment the first night.
There are a number of elevators. Half go to the lower floors, half go to the higher floors. Only one elevator was working one evening and it took a long, long time to get into the elevator and to my floor.
Very crowded. There were lots of tour groups and conference attendees at the hotel. That added to the strain on the elevators and public areas.
