Yes, but I'm not the right person to provide feedback as it's been ~10yrs since I last stayed there.
You're best off asking in the Hyatt forum... I'm sure the hotel has a thread going.
I think it was a very nice place, although it's good for what it is... a chic property that's perfect for r&r and obviously more incentive if you're a Hyatt person.
On the other hand, if the onsen is your priority or you want a quintessential ryokan type experience, it's probably not the place to go.
