Our party of five stayed at Meri's place.
The communal space for eating, watching TV etc was excellent with good technical facilities and plenty of room even for five. The bedrooms, on the floor above, were fine.
The neighbourhood is outstanding with clean streets and a very safe feel. There is a very good supermarket 10 minutes walk away.
Although some distance from central Boston, a combination of bus, which passes the front door of the apartment, and subway gets one downtown in 25 minutes and, for holiday makers, adds to the fun!. We came in a car, for which Meri provided a parking space, but did not use it until we left.
Our only reservation would be that the two flights of stairs in the apartment are pretty steep. and people who are infirm may find them difficult, particularly moving luggage.Similarly, the bathroom and the bedrooms are on different floors and this may be a problem for some.

However, overall we really liked the apartment and the neighbourhood.
