I stayed here specifically for the sauna.
It's the least "love hotel-like" love hotel I've ever stayed in; the room was clean and the facilities were excellent.
There are various discounts available, making it cheaper than the listed price, so I think it's good value for money.
The sauna itself is big enough for two people if you squeeze in, but it's better suited for one person at a time if you want to relax.
The temperature is just over 90 degrees Celsius, and sauna mats are provided.
The cold plunge pool is the type where you fill a bathtub with tap water, but the tub is spacious, giving you a luxurious feeling.
There's a fan, presumably for cooling down indoors, even at this time of year, which is a thoughtful touch.
I checked in late at night and was attended to by a male staff member, but he provided service comparable to a business hotel.
I will definitely be returning.
