Not Hyatt standard
Booked two nights as I was arriving around midnight on a flight from LAX. The first problem was that every other airport hotel had shuttles circling the terminal. After 15 minutes and no sign of the Hyatt bus, I called the hotel and they sent it over. When I got to the room my first impressions were of a very tired property that had not been renovated in many years...Maybe some carpet and furniture replaced, but the bathroom looked original and what you would expect of a low grade motel and not a major brand. There was also a area of the room where a piece of furniture appeared to be missing. I then attempted to order room service and was told that room service had closed. Eventually after complaining, the manager said he might be arrange some Chinese takeout!!!...then I went to look for the mini bar only to find there was none. 
I'm a Hyatt Gold Passport member and have stayed in many Hyatt's throughout the world so I'm aware of what to expect. Considering this hotel is located at a major international airport, the absence of both 24 hr room service and a mini bar is totally unacceptable. 
I accepted that I had made a serious mistake booking the Hyatt Harborside and was ready to check out immediately. However, as it was now 1am, I decided to endure till morning with no dinner. I checked out at 8am and moved to the Mandarin Oriental, which is clearly one of the best hotels in Boston. 
Hyatt should be ashamed to put their name to this dreadful and substandard property.
