Pros: excellent location, very clean, felt safe and secure, quiet, privacy even though renting a room of a condo, assigned parking spot, quick reply from the host.
Cons: the unit is on the top floor and gets very hot. We visited Kona on the week of July 4th and the heat was too much even though we are used to the hot and humid weather of Houston. The host provided 2 floor fans and 1 table fan. But when the unit is too hot multiple fans just blow hot air. The room stayed hot till 1 or 2 am with all 3 fans running and all windows and doors open for cross ventilation. We were hanging around the pool as long as the pool was open to escape the uncomfortable hot temperature in the room. A portable air cooler will solve this problem during summer time. The room also felt pretty tight with a king bed for the size of the room. The luggage had to be put inside the room on the floor as the closet was occupied with a dresser and a microwave and small refrigerator on top of the dresser, which left not enough space inside the room to move around. A full size bed will be a better fit for the room.
These are based on our experience and need and not necessarily will be the same for others.
