It was one of the BEST hotels I have ever experienced: a great building with over 100 years of history, classic, clean, great rooms and excellent service. As for the rooms, we were actually upgraded, so the impression of the rooms is more than the normal ones. But I think everyone can feel that the service is excellent. In some hotels there is often a strong pressure to tip for great service (I am Japanese and tipping is not customary in Japan), but I didn't feel that at all at this hotel, and I felt sincere service from the smiles of the staff.
To be honest, I don't even want to tell people about it because I don't want it to become too popular, but I'm writing my impressions here to express my gratitude.
