Wow what a great place.
It is exactly as described. One room with a bed, dining area and a kitchen. It is really perfect for visiting Boston. Clean and neat inside and out. The view is incredible. While enjoying coffee the first morning there, the Navy decided to move the USS Constitution which we were able to watch from the big window. The kitchen is well maintained and the location is just a short walk to incredible restaurants in the North End of Boston, or little bit further to Quincy Market and the waterfront. Also a short walk across the bridge to Charlestown and Bunker Hill.
I would strongly recommend this property.
