We had a great time in Ludovica's house. It is ideally located, with a private access to the beach. Ludovica's friend Giuseppe was also very helpful during our stay - taking us from & back to the harbor so that we don't have to drag our luggage all the way.
The house is nicely decorated & very clean. The only disappointment was the absence of Wifi when we came, which was unfortunate as 3G coverage is a bit unstable in the area. But let's be fair, this is not why you would come to Stromboli!
All in all, a great pick for a stay on Stromboli!
