Small rooms but great location
The Charlesmark is right in the middle of the Boston shopping and business district, and only a 30 mins walk to the university campuses at Longwood. Location-wise it couldn't be better.
While the rooms are rather small they have comfortable beds, free wifi and great showers. The free 24/7 coffee and tea, plus complimentary breakfast (bagels, pastries and OJ) are nice touches.
