Paul and Larry could not have been more welcoming or more thoughtful - they were really excellent hosts. The private apartment is well appointed with lots of thoughtful extras that really made us feel comfortable. For us, the real highlight was the back porch overlooking the garden - perfect for a morning coffee, an afternoon read or an evening drink! The neighbourhood was quiet at night and we felt safe at all times. We found it easy to get into Boston or out to restaurants / stores etc. It is a long (-ish) but easy walk over to Harvard - MIT is closer and some of the Boston tram tour operators have stops nearby. We didn't move our car from the much-appreciated off-road parking space for the three days of our visit.
We would certainly stay here again for any future trip to the Boston / Cambridge area.
