We had a group of 10 that stayed here for Memorial Day Weekend and it was perfect. The house is in great shape and is such a close walk to downtown and/or the beach. There really is no need to even bring a car as you won't even use it!
Also, the house comes with a great deck and backyard so were able to enjoy some of the nice weather for a little backyard cookout. I'd recommend this house highly to anyone looking to stay in Nantucket!
