Iian duenasheads up if you are assigned a smoking room, you will smell cigarette/smoke odor across the hallway and inside your room BUT, except for this i had a very comfortable stay at this hotel.
the room is warm during the day, i didn't have to the heater. i like the floor. the bathroom was very clean. the bed is big for one person. they have free breakfast where you can have rice, a variety of dishes and also bread (no need to show meal vouchers/coupons, they have complementary coffee from 4-10 pm. it's near the kushiro station/bus terminal. a few meters ahead, there are supermarkets and drug stores and 100 yen shop. the staff were nice.
