We had a wonderful stay on Alicudi! Julia was extremely responsive and helpful, and Lucia was an amazing guide. In particular, she helped us book two activities that we'd recommend to all visitors: a boat trip around the island, and a dinner at a local cook's house (which was delicious!). The island is a real treat: beautiful, with few tourists, and perhaps the best swimming we've had in Europe!
The caseta is very nicely set up: the small kitchen has everything you need, and we loved the two hammocks (one each!). The walk is indeed pretty tough, as Julia describes, but at the end you get a spectacular view and incredible peace and quiet -- we actually had the whole 'village' (it's really just a few houses) of San Bartolo all to ourselves! We have never been anywhere that is so quiet at night. Thanks Julia, Richard, and Lucia!
