Overall the stay was good. The room did not have a shower or bath and I realized it after booking a room “with toilet”. The concept seems that they rely on people going to the public bath located on the first floor and seventh floor for showering and bath. There is a room without toilet, too. So, be sure to select a room with a toilet and shower box if you can. The location is 22 minutes by foot from Awa Kamogawa Station, but you can simply take a cab, about 650 to 850 yen.
Breakfast add-on is great if you like lots of choices of Japanese food. Make sure to add it when booking as it is much more expensive to add on at the hotel.
