I stayed here recently. Very pleasant experience, starting at the check in where I was given a welcome champagne. The room is spacious. The hotel pools are gorgeous, and the lake front/beach is amazing. Good variety at the breakfast buffet. The food at the blue restaurant was also excellent. There are two restaurants a few minutes walk away, both by the lake if you want to eat something else.
Btw, the hotel is not on a lake, but on a bay of the Adriatic Sea (
Boka Kotorska)
