Had a great stay here! The room was beautifully styled with tatami and was probably the biggest hotel room we've ever had in Japan, being almost the size of a small apartment. The views around are simply breathtaking, and even if it is an older building, it is very well maintained. The onsen areas are fantastic, and if going with a partner, I'd highly recommend booking one of the private ones if available. I'd also recommend booking the breakfast buffet, as it was very good with a great amount of options.
The staff are the best part, however. Immediately we felt welcome, and they were always attentive and ready to assist with anything. They're the real sunshine here! Would gladly come back in the future.
