Stayed at HR Cambridge twice this summer. One time got upgraded to exec suite and I e time queen with terrace. Rooms are adequate but old and nothing fancy.
Breakfast tastes good but is super slow at times. I mean really really slow.
Gym is excellent. I studied in Cambridge so I'm partial to staying there and would again. But if I didn't have that personal reasons, it's just an ok spot. Overall,Hyatt is weak in Boston.
