Cozy Coffee House
The new Render Coffee in the South End is less than a mile away, in the South End--a very nice walk. I haven't yet been so am not sure about coffee house, but they are certainly serious about their coffee. Pavement is not so far away either, and has great coffee and a fun - if youthful - atmosphere. The Espresso Royale Cafes are also nearby. They own Pavement and have fans too.
