Why only 2 stars?

Why only 2 stars?
Quite simply because .... extremely unfriendly staff. One should know before you run around the opera x times and in vain at the main entrance is that the tickets are in a good 25 meters away back of a cafe to acquire. No matter if for a performance or a simple visit. In my opinion too overpriced, you have to buy a photo license, if you want to take pictures in the opera. Incomprehensible!!! Whether the stories told by the tour guide is true is set. The opera itself is beautifully restored.
