I think there are 2-3 Korean employees. The facilities are very good.
If possible, it would be a good idea to get a room with dinner included.
We ate outside and came in, but it was quite uncomfortable.
20 minutes walk from Yufuin Station to Baien Ryokan (If there is no hotel pick-up service, a taxi would be easier.) Please note that food is not allowed.
The hot spring can be used after 15:00, but the hot spring water is a bit lukewarm at 15:00. If you use it immediately after checking in at 15:00, you can use the family bath.
It's farther from tourist areas than you might think.
