We had a fantastic stay here in October 2012.
The house is beautifully old - and our room was very spacious and comfortable - and yes, a fantastic spa bath (jacuzzi).
The hosts were very friendly and had great tips for Bar Harbor, including a great restaurant where we could have Lobster. Nothing beats local knowledge.
The location was perfect too - walking to everything in Bar Harbor and we cycled easily to Acadia National Park.
The breakfasts were delicious - some excellent home baked treats.
Can really recommend this place!
