"This was my second stay at this hotel. It's convenient to Princeton University. It has plenty of parking. It's a good but not great hotel.
The breakfast buffet is decent and was included in my rate. However, DO NOT pay extra for it. It's standard instant-scrambled eggs, sausage, bacon, and a selection of cereals, toast, etc. like you see at any business traveler hotel. Everything is help yourself except: For some odd reason Hyatt Princeton gate-keeps the coffee and water. You have to rely on servers to come by your table for that. And they expect to be tipped. That's annoying. I just want to go downstairs, eat, drink some coffee, and get on with my day. Having to wait for table service at a buffet is just unnecessarily fussy. We skipped it on the second morning and went to Dunkin.
I stayed in two different rooms. The first room I was given (#420) had something wrong with the AC. When the compressor turned off, there was a loud BANG almost like someone was slamming the door. Regrettably, this happened every 25 minutes. My wife and I slept poorly. In the morning, I explained the issue to the front desk. They switched us to a different room and we had much better night's sleep. Both rooms were frowning a bit and needed a refresh (on top of AC service for the first one). The second room had a cracked sink.
Only one elevator was in operation during our stay. We took the stairs most times. Hopefully, they start investing in this property."
