I think the coast is close and the best location. It is an old facility, but it is pasted with tatami mats so that you can walk barefoot all the building. There are two baths in the morning and evening replacement, but the scale is completely different, so I can't evaluate if I don't enter both. I think it's not possible or impossible as a whole.
Very good, Christmas also gave a small gift, the service staff is very warm. It is very close to the Jisheng Sightseeing Center Station, it is very convenient to go to the Mizi Station, and there is a family opposite.
It was super convenient because I took the bus directly from the airport to Kaike Onsen, got off, and the hotel was less than a 5-minute walk away. It's also close to Kaike Beach, which was great for an evening stroll. There are some surprisingly good restaurants nearby too. The hotel itself definitely shows its age, especially the wallpaper... (And the group in the room across from us was really loud; the soundproofing isn't great ㅠㅠ). However, the room was incredibly spacious, and the heating was already on when I checked in, so it was nice and warm. I especially enjoyed relaxing in the public bath. Although I slept on a bed, the tatami living area gave it a lovely Japanese ambiance. Considering the price, it was an overall satisfying stay.
