Stunning hotel, we were so excited to stay here and were not disappointed! Lots of space and it was nice to see a more traditional style room. We had dinner on site which was a great experience, we weren't a fan of the food but it was due to personal taste rather than any fault of the restaurant, the staff were excellent. The Onsen was fantastic, to have one to yourself and relax with your partner was really appreciated. We used the indoor and outdoor onsens and they were both lovely. Location was quiet so we didn't hear any traffic, although the building makes it easy to hear people walking around so bear that in mind if you are a light sleeper. I would recommend getting to check in on time to get a good slot for your onsen if you like to go to bed early. We went in March and the room was cozy and not too cold/hot, however the bathroom was very cold so something to be aware of. We only stayed for a night so showered at the Onsen before bed. The beds were cozy, not very comfortable if you are a side sleeper, but fine for back sleepers. We knew this would likely be the case and didn't mind this at all for one night, we were just excited for the experience. Overall I would highly recommend staying here, it is unlike anywhere I have stayed before and was a nice way to slow down after a busy few days in Tokyo.
