We had a 3 nights stay in a semi-double room, and while we had expected the room to be small, we recommend that you should upgrade to a larger room.
Despite being very small in size, the room tried to incorporate everything in it,e.g. a cup on a hotplate to boil water, TV, a bath tub, a small tv.
We picked up disposable shaver from a small container placed at the lift lobby, and extra pillows from the pillow stations. For ladies, do remember to choose your amenities early, as some of the items may run out. It was definitely useful that we get to pick what we want.
While it was a bit of a walk between the hotel and JR Takamatsu Station, it was within walking distances to many restaurants. We enjoyed our dinners in Takamatsu very much.
Buffet breakfast at the hotel was very affordable, with plenty to eat. In fact, the hotel room prices were also very affordable.
The hotel staff spoke reasonable basic English, sufficient to communicate.
The not so good:
The room was quite dated, and some things were in need of replacement. I had to tug the wire a little for the hair dryer to work. The humidifier in our room had water inside it from long ago, and the metal bits were oxidised. We did not attempt to use it, since we did not find it critical. This might be just pertaining to our room though, as our friend in another room had hers working perfectly fine.
It was abit difficult to get the correct water temperature for shower, and it was winter... So this was really a big minus for us.
