Great location! We attended a wedding at the Haversham during our stay, which was under 5 minutes away. We also visited Mystic which was about 15 minutes away.
The house itself was pretty much as advertised, and was enjoyable for 5 adults and 3 month old baby. The 3rd upstairs bedroom had one single bed, not two, so plan accordingly. Still plenty of room though, with 2 queen bedrooms upstairs, and one in the basement. The TV downstairs didn’t work, which was frustrating, because the upstairs couch did not seat more than 2 people comfortably.
Overall we had a nice time, and enjoyed our stay!
