Luca is a nice person and communication with him was great. The apartment is really simple, but nicely located and somehow what you can expect at a remote volcano island. Luca's advice was helpful and somehow "saved" our trip to the island, as we couldn't climb the volcano due to bad weather.
Nevertheless the price is ridiculously high for what you get - despite being in line with the general price level on Stromboli. We payed the same amount for a suite in a 5-star luxury hotel with breakfast in Valletta, just one night later.
