Kit and Scott are wonderful hosts. Their warmth and friendliness are exceptional. They will give you lots of great tips on sightseeing. The T station is three minutes away. Also there is a great restaurant (evergreen) very close by.
Kit took me on two bike rides that I really enjoyed. She is so knowledgeable about Boston and so is Scott. Also, they will invite you for a glass of wine or to watch a movie with them. It felt more like staying with family than with strangers. Highly recommend this place. I would stay again!
