My wife and I attended the FilmFestZell in Zell am See and we stayed one night only. The staff was extremely nice and helpful and also the breakfast was great. The room very clean with lovely interior and very quiet.
I only have one tiny little complaint: We wanted to go to the sauna in the hotel but it only opend at 3pm, that was to late for us. Still this was more a mistake on my side since I didn't really asked for that info. The pool and gym was open, just the sauna closed.
Still we had a great stay and I'll guess we'll come back for sure.
