Good Location, Great Value, Friendly Staff
I recently stayed in this Hilton Garden Inn in Chelsea with my wife and 2 kids. The room was larger than I had expected for a NYC hotel. Still a bit tight for 4 people, but not uncomfortably so. The staff were very attentive and responsive to requests for additional towels, etc.
We generally had breakfast at the hotel buffet (kids were free), which was a better value than getting an equivalent meal at a nearby restaurant. The 28th street subway was right at the end of the block. Very convenient! There was a sushi restaraunt and a McDonalds within the same block. Walking distance to the Empire State Building and the Amtrack Penn Station. Lots of flower shops, so it was a festive atmosphere. I'd definitely recommend the location.
One quick story: On our last day we checked out bags at the desk and decided to have breakfast out at a nearby diner (again, not a great value compared to the buffet). At breakfast, I noticed my wedding ring was gone. Oh, $#@%@. A rapid search of the restaraunt turned up nothing. We returned to the hotel, but the maids had already cleaned the room. The manager allowed us to search the room, but no dice. Very dejected, we nevertheless continued on our planned trip to the Metropolitan Museum of Art (I highly recommend it).
We returned to the hotel to pick up our bags and head over to Penn Station to return home. The manager said, "Hey, didn't you lose a wedding ring?" Yes, I said, cautiously hoping. He gave a big grin and produced the ring!!! They had found it in the laundry room wrapped up in a towel from our room. Evidently it had come off while I was drying off. I was so relieved; it would have been very bittersweet coming home without my ring. They wouldn't accept a reward, either! 
Needless to say, we wouldn't hesitate to stay here again!
