We were in 2 adults, 1 child of 8 and other of 3 years old. There were 1 double and 2 single beds, so for a family of 4, it was perfect. In the bedroom, there is AC with timer, which was very helpful to sleep at night.
This is not a hotel, so do not expect room service, but still they provide clean towels and sheets whenever you like. They have an external room with any of these items accessible 24 hours. In this room, it is also possible to use the laundry machine, with washing powder also available free of charge.
One of the interesting things about this place is that they have a kind of greenhouse for growing mushrooms, and we can take it to eat whenever we like, as long as there is any to take. They also have some herbs and vegetables growing, and since there is kitchen to cook, we used it quite often in our meals.
The wi-fi there works quite well. At night, we could watch youtube videos without any problem. They have cable TV with not many channels, but unexpectedly they have the Japanese channel NHK, which was useful to my wife since she is Japanese.
There was no supermarket at walkable distance, but you will need a car to go to the many beaches of this island anyway. The best option is a supermarket called Angeloni in the main street. This is the biggest supermarket, and is not more than 10 min by car.
For the price paid (39 USD per night), I believe we could not ask for more.
