My husband and I stayed 2 nights with Penny and Stu - they were amazing! Their house is beautiful and the room we stayed was clean and had a wardrobe which was really helpful. The internet works fine. The house is close to the main beach - 15 min by car/taxi ($20 fare), 20 min by bus and around 1h walking. Also they have 2 handsome and lovely dogs!
I recommend them for sure. My first experience with Airbnb couldn't have been any better.
