Pros: Great location - easy to walk to Faneuil Hall, Aquarium, TD Garden, lots of restaurants. Communication with host was easy and response time was fast. Apartment was clean and as described.
Cons: Futon for extra person not very comfortable for sleeping, apartment could use new towels, shelf in bathroom broken so no place to put personal items, five narrow flights up may be challenging for some people and/or folks with heavy luggage.
