Dear Elena,
I'm Paola the soprano of the Roma Opera Omnia Ensemble
I am very sorry about what happened and that you didn't find the place because the address was not correct on Viator where you booked the event.
I'm so happy to hear that you enjoyed our concert
It was a pleasure for me to have you at our event!
We waited for you 10 minutes before starting so you missed only the first two musical pieces :)
However I would like to point your attention in what is included in the "Opera Dinner" ticket.
I copied it from your voucher of Viator where you booked.
As you can see there is no guided tour listed because there isn't an art gallery to visit.
-Exclusive and private entrance in the Innocenzo X Hall
-Welcome Aperitif
-Candlelight Dinner: two menus with Italian specialties, included a bottle of selected italian wines
-Opera concert before Dinner and between courses, with final toast with the artists
-Music presentation in English
-Entry/Admission - Eitch Borromini
Guaranteed to skip the lines
Booking Source: Viator
So I'm sorry about the misunderstanding and I hope to enjoy your company again!
Un caro saluto Paola
