Dormy Inn has long since been my absolute favorite chain of hotels in Japan. They have offered me comfort with their onsen-hotspring style baths after my long motorcycling tours. But their Soga location has severely disappointed me. The hot spring's size is a fraction as usual, and the quality of the water is disturbing. There is a black residue all beneath the waterline and there is a heavy smell of ammonia or sulfur. So much that my nose burns. The rooms were not so clean as well. Dormy Inn Soga is an outlier to the usually excellent hotel locations of the Dormy Inn name.
