This is a grand old hotel right on the waterfront in Brunnen (the main Brunnen boat dock is literally outside the front of the hotel). Despite the passage of time, where it matters, the hotel has done a great job. The rooms are spacious and comfortable. They have astounding views (if you have a "mountain view" room and all you see is the hills behind town, crane your neck a bit and you should see the Grosser and Kleiner Mythens). The restaurants are modern. The breakfast is outstanding, with little touches that are almost knowingly ironic, like prosecco with vegetable juices on offer. The WiFi was of high quality.
Their dining menu is absolutely modern and the service, just like at breakfast, is outstanding: proper and solicitous, not what it could so easily have been (stiff or snooty).
In short: a delightful place, well worth the cost (which must be judged by Swiss standards), meeting and exceeding expectations, and worth a return visit.
