I enjoyed my stay at Anh's place. She greeted me upon arrival and was very friendly, as was John who I met the next day.
The room is attached to the main house with a separate exterior glass sliding door and one interior door that leads to the main house. It was fresh and recently updated, very clean. It does have a private bathroom with step-up shower, which was a nice plus. No A/C but there was a ceiling fan and floor fan which kept the room cool enough. Also, be aware there is no TV, for those who care.
Location is a short drive above Kona town, near the shopping and restaurants. It is a working class area and very quiet at night. No loud music or barking dogs...
Parking is at a premium on their street but they did have a driveway that was literally a few feet from the door to the room. A bit narrow with rockwalls on the drivers side but I got in and out without too much trouble.
I did not get to spend much time with my hosts but they were very gracious and friendly, making sure to ask if I needed anything. Overall, very pleasant stay!
