Just returned from a weekend in Mystic for a wedding and stayed at the Whaler's Inn.
We were in the Main House, located above the lobby and right on Main Street. Even though Mystic is small, you could hear a constant stream of car traffic in the room. You could also hear every time some one moved upstairs, spoke loudly downstairs, went down the stairs, etc. The room was very small and uncomfortable; the mattress was too soft and worn down.
The room was also very hot. We turned off the radiator and opened the windows - in the middle of winter it took several open windows to cool the room down. The radiator also whistled throughout the day and night - waking us up over and over. That, along with the car traffic, lack of decent blinds or curtains, made for the two worst nights of sleep I've ever had in a hotel.
We spoke to the front desk about the radiator noise and they explained that just happens but they would "look into it" .. as if that meant anything.
The breakfast wasn't anything special. The restaurant next door, Bravo Bravo, was great for lunch.
The only caveat I will give to this review is - we don't typically stay in B&Bs or Inns or whatever. I would rather be in a regular hotel (both the Hyatt and Hampton Inn are located close enough to downtown) and get a good night sleep that be in a "quaint" but rickety old house. The only, only redeeming quality about this place is its location - very near downtown.
