Close to the date of our reservation, they messaged us details on numerous details including how to check in, being very thorough in how to get to their place, and leaving no stone unturned. Upon arriving, checkin was smooth, as it was exactly as described. The room was beautifully decorated, and the complimentary snacks and drinks made the experience even better as we didn't have to worry about finding a convenience store to buy water.
I would definitely recommend Boris & Susan's place to any traveller planning on staying in Boston!
