It was very easy to communicate with Bernard.
Check in and check out were easy as well since Bernard uses a lock for the keys. It was a very pleasant stay, the amenities are good and the place was very clean, not to mention that here is a huge TV of great quality with cable channels.
We were staying there for a business trip and we rented a car to go to the convention center everyday. It was a great option since there is free parking in front of the house and the place is located 10-15mn to the center of Boston. I heard Dorchester wasn't the best part of Boston but the location was just perfect for us and seemed safe as well. I recommend staying at Bernard's.
