We stayed at 20 Lily in August 2015, and we can't say enough good things about this house. It was perfect for our large family (8 adults, two toddlers and one infant)-- perfect layout such that we didn't have to be in each other's hair thanks to multiple sitting rooms, three floors of bedrooms and several decks. The house was so well kept-- we couldn't possibly have needed anything else in the kitchen; there were tons of towels, nice linens, beach supplies, etc. Mary Ann was a pleasure to work with-- very responsive over email, phone, etc. She even left us cupcakes and a set dining room to greet us! The house is extremely well located-- convenient to the ferries, downtown, Children's Beach (where we went every day), restaurants. We took cabs to other parts of Nantucket and rented bikes. It was perfect. We'd stay here again in a heartbeat.
