I've not been to the No Stress Pub. I've been to Sirmione and it's a beautiful place. The castle is worth a visit as it's partly submerged in the sea which looks cool. Visited Acquaria Terme which is highly recommended if you like spa stuff. We went in late afternoon and watched the sunset from the outdoor jacuzzi with a Hugo spritz. We stayed at Hotel Meridiana which is just outside the north end of the town. Their food is absolutely outstanding. We stayed three nights and ate there for two of them. The lady makes all the cakes and they're outstanding. It was my birthday while we were there and I got presented with a chocolate cake with a candle in it which was a nice touch.
Sounds great @becs .I've not been to that Pub or the hotel....but the Sirmione area is amongst the finest in Europe,imo.
