    This was my second stay, and I was very satisfied—both the meals and the staff’s hospitality were excellent, just as expected. The bath felt slightly lukewarm, but that made it easy to soak and relax, and I could really appreciate the high-quality water. I heard renovations to the bath are planned soon, and I would definitely like to stay again.
