Right at the centre of Hirafu - you have to walk a bit upslope to the ski lifts. Check in is at another building / hotel so beware if you're not driving.
The space is well equipped with a full kitchen and washing machine, as well as heaters. There is also a ski locker on the ground floorwhere you can pit your ski equipment. However we noticed a smell of fresh renovating works once we entered the room - though we're not sure where that came from.
If you're driving, beware they only have 2 parking spaces in front of the building which are not designated for guests. So if someone else parked that space, you have to find somewhere where you're not considered a hassle. Note you are not supposed to park behind the building nor the space next to the 2 parking spaces.
