I had a very nice stay at Philips house, which is in located in a nice residential neighborhood area half way between downtown Boston and Harvard. The house is easy to reach via the subway and Phil gave clear instructions how to find everything. Within walking distance there is a Bagel store (1min), Whole Foods (5min) and all the High Streets shops (7min) as well public transportation.
Even though I could not meet Philip in person, he promptly replied to any question and gave recommendations for restaurants and bars. The apartment itself is in very good conditions and as described by Philip. I stayed there for two nights and it was really easy going. Basic breakfast ingredients (Coffee, Milk and Cereals) are available in the kitchen and the bathroom is shared between the three rooms that are rented out. If you look for an easy to reach location to discover Boston and Harvard, that is a good place to stay and the neigborhood is nice. It is not the old-fashioned type of B&B, where one lives in the same apartment with the owner, constantly interacts with him/her and have breakfast together every morning.
