I can recommend Kevin's apartment wholeheartedly. It is a very spacious and well-appointed 2 bedroom. Kevin is an extremely gracious host who makes sure his guests are comfortable.
The location is great for families or any tourists really. We had a rental car but hardly moved it for three days since we always used the very convenient train to get downtown and to tourist sites.
The apartment is well-furnished especially the bedrooms. It is not one of those airbnbs where all the furniture feels like leftovers and second-hand stuff. There is interesting art and its just a good vibe overall. If we get back to Boston, we will definitely try to stay here again.
