The venue was well chosen for the music genre. I consider the selection as average, some of the songs didn't catch me, others were captivating. The artists-performers were good, especially singer-soprano and organ player.
However two main issues with the whole performance were following - the seating was faced towards the main part of the church, which is understandable (you won't rebuild it. But at least a notification would be recommendable. The other spectators were very confused, that they should face empty space, when performers are behind them. Plus I would like to mention that to turn on some chairs made loud screeching sound, the chairs were really old!
Second issue I had was with heating. There was a line in the event description saying the venue is heated. This was provided by heat lamps, but after you turn them off in 20-30 minutes the cold is back. So either turn them on way before, or try to find a way to let them on during the show, or just change the description!
My experience was affected by other spectators who started to be restless after a while (really taking your 2 small children to a concert of classical music is a great idea) but this was mainly due to the fact, that they couldn't see the performers without turning around.
