I stayed in Traditional Apartment - Hostel for 2 days in April 2017. The staff were very friendly, polite, and helpful. In addition to introducing the hostel's facilities, they also gave me detailed advice on the popular tourist attractions of Takamatsu city and the schedule of shuttle buses to Takamatsu airport.
I booked a bed space in one of the hostel's dormitories and it was both tidy and comfortable. There were a kitchen and a washing machine for my dorm. The only drawback was that there was only one washroom and one bathroom for two dorms combined (around 6 people in total), but this is acceptable in my opinion given the affordable price.
Overall speaking, I think this hostel is of good value for money and will recommend it to anyone who looks for a clean, tidy hostel with friendly service at an affordable price.
