It is a very nice property with a nice view, but suggest that you book 1F rooms if not you will not have any view.
I booked Japanese Western Style Room with Half Open-air Bath, 1F. The onsen in the room is really nice and so enjoyable when you are back after a busy day of driving around. The location is good too, very near to Beppu city in a few minutes by car. Also suggest that you rent a car, it is much easier.
The breakfast is really good too, the pure Japanese tradition, the restaurant room has a beautiful view too with large windows. We had dinner as well, which is also very good.
I have rated cleanliness poor, because our room was not cleaned on our second day when back at around 56pm, we were told that they forgot (although only 2 rooms were occupied, it was not a busy time). For the price tag (SGD360 / night) cleaning a room is not something that can be missed. I expect the room to be cleaned. Since it was after 6pm they simply removed the trash but they did not tidy the room up, a bit disappointing. Without this issue I would give a better rating because all the other aspects are good.
