Three friends and I attended the concert in Kursalon recently. The building and interior is beautiful. We had booked seats in the C section at a very reasonable price but as the venue was quiet on the night we were able to move forward into the back of the A section. Regardless of seat, as the venue is quiet small, all seats are good. The concert was excellent and we all felt that it was the highlight of our trip to Vienna. Would highly recommend it.
