Excellent location for transit passengers. On the opposite of Shin-Yamaguchi Shinkansen station, across the road. Breakfast is excellent, in the room too everything is, cozy and clean. The mattress is comfortable, the pillows are also. There is water in the cooler downstairs.
There's nothing to regret... that I didn't have time to try, but the service was friendly and everything was playing... a little sterile hall, but otherwise everything was okay.
It's a little far from the hotel in Yuta Onsen, but the exterior was beautiful, the interior was elaborate, and the food was very delicious and satisfying. Cospa is the best!
