To begin with, the shuttle bus from Odawara station was 15-20 minutes late with no communication to us.
The rooms and public spaces needed some tending to (worn carpets, AC that didn't work, etc.)
There was no bar at the hotel--and the staff treated us like we were crazy for even asking.
The buffet meals were fine--but definitely not for the price point.
There were very limited options for things to do at the property (no public sitting room overlooking the lake, no seats outside to take in the scenery, etc.).
The staff were not terribly hospitable--not rude, but definitely not concerned with hospitality. It is a hotel with great potential that is poorly managed.
All in all, quite disappointing for the price (over $500/night).
