Absolutely amazing place, we had a blast of a time there!
Place is amazing, stunning lake views, lovely room, fantastic breakfast included, private beach by the lake, pool table (2 Euros a game), fussball (1 Euro), darts and blackjack table available.
All in all amazing place, best one I've stayed in so far.
Only downside is getting there, as it's quite remotely located, so if you're not driving might struggle a bit, but there are definitely bus connections from Annecy.
