You cannot beat this location! Just steps from a metro-line or you can walk and within 15 minutes be at the water, Italian district, or anywhere else you'd want to visit in Boston. We had 8 adults and 1 toddler stay here and had plenty of room in the living area to hang out and relax.
The only downside is there were not as many amenities as other AirBnbs, we didn't find a cutting board and there were no staples in the cabinet. However, this doesn't really matter if you plan to eat out most of the time. Also, there is a grocery store within a block or two of the apartment so it was easy to pick things up!
