The quality of the seats depends upon how much you pay. Category B costs 35 Euros; Category A is 42 Euros; VIP seats cost 55 Euros; Premium seats cost 75 Euros. Go to the Palace of Music website to view the seating chart. The less a seat costs, the farther from the stage. Posts blocking your view from some of the cheaper seats. We were in box 8 on the right side of the stage. Each box has 7 seats - three in the front (Premium seats), 2 in the second elevated row (VIP) and 2 in the third elevated row (VIP). The box and the seats are very small and next to each other in the first row. The view and sound from where we were seating in the elevated second row were fantastic.

Explicitamente no lo hay, pero al menos pantalón, camisa y chaqueta sería de agradecer. No en pantalon corto.

There is a restaurant on site

I assume so. The guide is downloaded to your device.

We did not see a show; only the daytime tour. Perhaps email them directly.

Buona sera, Il Palau dispone di ascensori su tutti i piani per accedere ai diversi spazi inclusi nella visita. Grazie per il tuo interesse.

Das ist doch eher eine Frage für Google - oder ? :-)
