The best onsen and overall hotel experience I've had outside of Japan. The facility and amenities were superb. The included breakfast was plentiful and tasty, and the room service options were as well. My only concern is that guests can be quite loud. This ended up not being a problem, as the nude/gender-specific areas were quiet and many people use the nude ones. Additionally, if you're able, please splurge on the private baths/onsen. These baths in the room were my favorite. So quiet and peaceful around the rooms. The design was wonderful. My favorite part of my trip to Vietnam, and I would make the trip back to this area for the onsen alone.
