The Church is located between the village with it's postcard small streets and the beach packed with restaurants and little hotels.
It is a simple but quiet church and travelling from Sorrento, I met an old couple who wanted to see this church where they celebrated their daughter's wedding. How original and sweet!
I would recommend, if you travel from Sorrento, not to wait 2-3 hours in the queue for the bus (as there was a very long queue there) but to consider finding 7-8 other people at the end of the queue and pay 10 euros each to a small bus driver to take you to Positano. Not only your waiting time is reduced to 0 but your travelling time will be reduced by more than half. I had the inspiration/luck to come across such Italian drivers waiting with their mini buses near the train station and apparently you can book this even by 30min in advance.
I also learned that you should never consider travelling in rush hour to/from Sorrento/Positano/Amalfi. You should also consider taking a fast ferry from Positano to Capri and then Capri back to Sorrento. But always check in advance the departure times as apparently the Italian websites are never reliable.
