First of all: the place is quite nice and reasonably clean, absolutely okay for the price, BUT:
It is completely unsuitable for groups that don't just come to drink! We (8 people, mostly female) were crammed into the square with the other young people. The space for youth groups was overcrowded, there was nowhere to walk without stumbling over strings and the tent entrance was blocked for some! (people were still accepted anyway)
But the absolute blast are the rules of the area and, above all, how they are implemented: music is prohibited from 10 p.m., which is a bit strict, but still acceptable. At 12 o'clock sharp every evening a 'nice' gentleman stood in front of us and ordered us to go into the tent (because of the night's rest) and didn't leave until we really got up. On top of that, the security ran across the square several times during the night (only over the campground of the young people, mind you) and reprimanded everyone who was still talking (!) In the tent.
So no matter how old you were and no matter how you behaved, you were treated like a felon! I can only strongly advise against the place.
