This is a great place to stay for large gatherings! The house is as described.
A few things to note:
If you have a senior or anyone with ANY mobility, heart, or lung issues, this place is NOT for you unless you have a car. It is only about .3 of a mile to the forest hills line, but that hill is STEEP.
The T line is super easy to use from this location, but it does take about an hour to get from the airport to here (depending on traffic, about 20-30 minutes to get to the Freedom Trail).
The house is beautiful and in a quiet neighborhood. However, there is not a lot of comfortable seating options. The dining room chairs and the two chairs in the living room are very uncomfortable. Just something to note if you plan on gathering and visiting.
Everything else is fabulous. There are many restaurants and it is close to a walking trail in the Arnold Arboretum which is fabulous.
