The place is very comfortable for a solo traveler, it is very secluded, quiet and calm, good for those who want to work on writing or other projects of the thought. It is only 5 minutes walk to Lanikai beach, with all activities of rowing and snorkeling. There are at least 5 sea turtles living on the north end of the beach, just 50-100 meters into the water. It is also a short 10-minutes bike ride to Kailua and Kalama park beaches, with their windsurfing and wave riding activities.
Melissa is a thoughtful host, who will take all your needs taken care of. Check with her if you want to learn more about the sea life of the nearby beaches. There are several great hikes in the area, one of the Kaiwa ridge, just above the house, if one wants to make great sunrise pictures. It is a bit overcrowded compared to just 10 years ago, but Olomana and Demonstration trails are better hidden gems, so check with your host how to get there.
There is no shops in Lanikai, so one needs to use a bus N70 or Uber, or a bike, to get to Kailua to buy any necessities.
