Serena is a lovely and welcoming host, and everything about her home was perfectly as described. It's close to a main, busy street (another review said "just around the corner" - I agree), yet quiet and peaceful. A 10-min walk to the metro and about 15 minutes to walk to Harvard Square. The room has a giant bed and a TV mounted on the wall - there wasn't much space left after setting down our suitcases, but it was all more than enough for what we needed and great for relaxing after a day out in Cambridge. Serena also has 2 indoor and 1 outdoor cat, which made our stay more charming. Definitely recommend! Thanks again Serena.
