We made a mistake as we did not know that the Stromboli ascencion with Stromboli adventures only starts from Stromboli.
That is why we asked Pongolini to cancel our reservation 2 days before coming to Stromboli.
We are really disappointed that Pongolini did not reject the reservation neither advise us about other solutions when we told him we were coming to do the ascension..
Moreover, he did not even reply to our last messages.
This is the only bad memory we had from our trip in Sicily.
Really disappointed!
