I booked this hotel blindfolded through Priceline and checked off both downtown Boston and Cambridge. Next time I would check off JUST downtown Boston. This Hyatt is located on a beautiful quiet avenue overlooking the Charles River, which is nice for some, but not in the center of things as I like to be.
If you go, enjoy a nice cup of coffee and a dessert in Spinnakers. It is a revolving restaurant overlooking the river and skyline of Boston -- great at sunset!
For $56 a night, this hotel was a steal! They have a free shuttle that runs during the daytime hours that we found very convenient to get to the "T" and a few destinations nearby. The desk, concierge, and housekeeping were great.
The rooms were very clean and spacious. The bathroom we had was a bit small, but overall very comfortable.
If you get a great deal on this hotel you'll not be disappointed, but I would have been if paying full price.
