Hotel is in a great location of Takamatsu, pretty much city center. There are plenty of places to eat, bars, shopping street and very close to train/subway station which makes it convenient to go to main train station of Takamatsu, ferry port to Naoshima/Teshima/Shodoshima as well as mountains around (Bushozan, etc).
The rooms are a bit small compared to Western style but that’s kind of normal in Japan and in general OK for coming back from a day trip or excursion and just sleep.
