We really enjoyed our stay at Mary's place! Guests have their own room and bathroom and it comes with a personal fridge as well. Mary provides some amenities, e.g. cool drinks and some cereal bars. Bigger shops are 15 mins by car in either direction on the coastal road. Parking available in front of the house. Some beach equipment is also provided. I would say the place is a good base for exploring Northshore Oahu incl. Snorkelling, seeing Turtles, the Polynesian Cultural Center, Waimea Valley, Pipeline wave (only in winter months).
