We spent 8 days in Simin's beautiful house and e enjoyed every single one of it. Especially the mighty big veranda (lanai) and the beautiful view out onto the sea!
The house is big enough for a family gathering (we were 4 adults and one small child) and had plenty of space - 2 more adults would fit too!
Hilo as well as Kona are quite a bit away (45 to 60 mins driving) and the closest grocery store / market is at least a 30 min drive so one should think ahead and provision accordingly. There is a farmer's market but unfortunately we missed it! Next time ;-)
Highly recommend !
