We have agreed to be "upgraded" to Tui bach. The view was amazing! Nice and responsive host.
The shared bathroom was clean and decent but we struggled a bit to cook our own food in the shared kitchen: limited space in the fridge, limited cooktops/fry-pan/space in the kitchen for all the guests/campers, bbq not working...
Overall, for the price, it would be a good camping-like experience if we had planned to eat in a restaurant.
