We just spent three very pleasant days and nights at Ann's place. Upon arrival, Ann met us at the apartment with keys and to give us all the info we needed about the apartment, neighborhood, etc.
As others have noted, the place was very clean. It was also light and cheerful with lots of space. The living area had plenty of comfortable seating to accommodate our party of five, plus the two locals we were visiting.
We have stayed in numerous other Air BnB's and, by comparison, Ann had done an especially good job of stocking the place with beverages, snacks, and everything you need in the kitchen and baths for a convenient and comfortable stay. We did not need, but there was lots of great and nicely organized information on things to do in Cambridge and the Boston area. Communication was very prompt before and during our time there. I would highly recommend this BnB, and we would definitely stay here again.
