tiny issues - as long as you remember that only half of the rooms have been refurbished, make sure to get one of those !
WiFi coverage on the cafè terrace and in the rooms in the first floor was a bit weak.
dinner was good on buffet nights, lacked a bit of variety on other days; there's room for improvement here.
and yes - the "60s design" of the lobby is dated, very dated.
the location is breathtakingly beauiful, rooms are very comfortable, views are hard to beat, you feel like sleeping in the middle of the lake; beach is nice.
but, above all: this isn't a small boutique hotel - but the staff makes it feel like one - impossible to single out anybody, all staff members from bell"boys" to the impeccable and quick service at the beach and the restaurant, everybody was doing the best possible to make you feel welcome and comfortable. impressive.
