About this home

This charming two bedroom cottage is located out of the prevailing winds and has great sun. Watch the Mount Washington cruise by! Open concept living room and kitchen. The beadboard half walls add to the cottage feel but this one is all about the wrap around deck with 552 square feet of space. A great spot for family memories! There is also an additional deck by the water, great for morning coffee! Rattlesnake Island is an association island with fantastic mainland amenities including a pick up and drop off dock, parking lot and boat ramp. In addition there are hiking trails on the island to the top which provide spectacular views, worth the hike! This one will not last!
