We stayed for one night with about 15 people.You can see the sea in the morning and evening from the perfect location with no obstructions, have a barbecue in the garden, and relax in the house afterward.It was probably built during the bubble era, and it was a very stylish and clean rental villa.Inside the house, there are two bedrooms with two beds on the first floor, a Japanese-style room of about 6 tatami mats on the second floor, a guest room with about two futons, and a large living room.When it was time to sleep, I separated the rooms into the bedroom, Japanese-style room, and guest room, and the rest of the time I laid out my futons in the living room and slept in the living room.As for the barbecue equipment, there are two large American-style stoves and plenty of charcoal stock, so you can use it empty-handed. I didn't check if there was a fire starter, so I think it's a good idea to bring it with you.Almost all tableware is provided, so I think it's okay to bring nothing, but if you use it, you have to wash it and put it back in its original place, so if you're a large group, it's better to bring disposable cups and plates. There are few.The bathroom is large and can fit about 3 people if you fill it with hot water, but the shower is unique and cannot be held in hand, making it difficult to shower on children. (The holes in the shower head are widely spaced, so it is difficult to flush without standing up.)It would have been nice to have instructions because the hot water doesn't come out unless you turn the handle to about 200 degrees.Actually, I think it would be better to collect it in a bucket and flush it away.There is also wireless LAN (Wi-Fi), but it is written in the PDF instruction manual and there is no password in the house, so it was a bit disappointing that people who did not know could not use it.It said that 3 cars could be parked, but if you pack a regular car, you can park about 5-6 cars. (Those who park first will not be able to get out.)However, on the day I checked out, an insane angler had parked his car there even though it was private land, so I had a hard time getting out.I worried unnecessarily that it would be better to attach warning signs and ropes.
