Great location, especially if you are doing the Stromboli hike. It's just below the meeting point so there's time to check-in before the hikes if you're on the 4pm ferry (Lucio told us that the hikes always start a lot later than advertised and he was right!).
The apartment is lovely and clean and the beds were comfortable. It does get quite hot so the apartment really could do with a fan as there isn't air conditioning and a bathroom mat would be handy too!
