I stayed at the Charles Hotel while at Harvard University for a conference. The hotel is perfect. No fault at all. Quiet and very spacious rooms (had one with double beds). Excellent room service. Excellent restaurants within the hotel and nearby. The free wifi was decent and worked in the rooms and lobby. The in-room safe worked well and the minibar was convenient. The location is ideal - near plenty of shopping and restaurants and cafes. A short stroll to the Harvard University buildings and main campus. Will definitely stay here again if needing accommodation at Harvard University.
