I have just read a review below that stated, "nothing I write will adequately describe the pleasure of staying in the Tower House" and I completely agree.
My friends and I were travelling around New England in the summer and after driving round Cape Cod, we stopped off in Rhode Island. From arriving at the house Mary Beth was so pleasant, helpful and welcoming and could not do enough for us. (To my shock the boys asked if it would be OK for her to do some of our washing that had mounted up from travelling around and she was more than happy to do this). Mary Beth took time to talk to us and get to know us over a lovely breakfast (I especially enjoyed the quiche) and even kept some wine and cheese etc out for us coming back at 9pm, despite the snack hour being at 6. The house itself its absolutely lovely filled with antique furniture and there is often fantastic music playing in the house throughout the daytime.
There are also little extras that make it great, such as MaryBeth is always happy to offer lifts to the beach if necessary as parking can be expensive, sweets and water, tea and coffee and morning paper in the hall and free computer/printing access.
I have never stayed anywhere that has been so accommodating as the Tower House B&B. I hope I get the chance to go back, but until then I will be recommending this beautiful place to everyone I know.
