Spent a very pleasant week here. We chose it because of its proximity to the ferry terminal, and it was perfect for this.
The hotel was great and we do recommend it. I'd have given it full marks except for the sulphorous smell of the thermal spa which permeates the public areas of one of the two buildings making up the hotel. It's not a show stopper, but it's something to be aware of.
Many positives though - the staff were nice, as was the room, and also the dining room. Sitting outside on the terrace in the evening sunshine with a drink, overlooking the lake, was lovely.
