Very quaint little place right on the water with their own, small, but private beach. They had 24/7 free coffee, and adorable layout/courtyard, friendly staff, and even free to use beach chairs, towels, various floats/lpool toys for the water too. Would stay again.
Only a 5 minute walk to the port authority, and very close to two car rental agencies (maybe more), close to some shops and restaurants. Also close to the Martha's vineyard bus stop.
