We stayed for 3 nights in October. Our room was fabulous. Lovely big bed, great sitting area, awesome views over Takamatsu. The service from front desk outstanding. Language as usual an issue but nothing was a problem. We sent our bags on from Hotel Bokaiso and all went smoothly. Meals are traditional Japanese and delicious and there is a 24 hour tea and coffee machine available.
The only issue is the location. We did walk to Ritsurin Gardens one day but it took about 3 hours. Not for everyone. There are taxis at Takamatsu, takes about 30 minutes but we chose to train to yashima and taxi from there. Beware no taxi on a Sunday from Yashima station! So we do thoroughly recommend this lovely hotel but be prepared to taxi to Takamatsu if you want to sight see around the area. Ps. A day trip to Megijima Island in the ferry and hire an electric bike great fun.
