We stayed at Rachna's place last week with my extended family.
1. Location was great, close to the airport, 15 min to Kona and 20 min to Waikoloa Village and it comes with chairs, umbrellas, boards which is perfect for the beach.
2. We rented the whole place. The home is compartmentalized, where the main house has 1 bedroom + the loft + the living room + kitchen. The king suite is completely separate and you have to go outside to the rotunda to access it. The queen suite downstairs has its own kitchen and a full size fridge and it was perfect for my mom who could have her own space.
3. There are no "windows" and it is very very loud at night; it takes a day or two to get used to listening to the frogs, crickets & roosters going off at 2am. The neighboring dogs barking in the middle of the night dont help either. Rachna does provide ear plugs which if you arent used to wearing them, can be uncomfortable.
Overall we had a good time and appreciated Rachna extending her home to us.
