The worst hotel I stayed at in Japan.
This hotel is extremely old, using a central air conditioning system, and you are not allowed to adjust the temperature in your room. During my stay, I had only two options: either turn on the air-conditioning system and endure an uncomfortably warm room temperature, or turn it off and open the balcony door to let in natural air, along with some smoke from other customers smoking on their balconies.
In the end, the receptionist could do nothing but lend us two fans. This was the first time I stayed in a room with "air-conditioning" stated on their website, yet I could only use two fans for my two-night stay.
Please avoid this hotel, as I believe there are much better options in this area.
