Book this hotel for 4 nights for the Boston Marathon. Fri-Tues. I lucked out and got a very good deal on this hotel with breakfast. We were able to check-in right away at 1pm. The room was on the top floor, rather large (we got the handicap room). Room was clean, no problems. Your typical Courtyard hotel. They even provided two bottles of Gatorade for the marathon weekend.
The free breakfast would not be worth actually paying for it. It provided us a free meal at breakfast that was it.
Close to Prudential Mall, Shaws and the Copley T, and Back Bay Amtrak.
