Valerio's apartment is in the best location, it's a minutes walk to the beach and it's right in the centre of the historic part of Cefalu. Before our trip Valerio and Daria were both very good at communicating through Airbnb, and our check in/out went very well. It was very hot during our two week stay so we used the air conditioning upstairs most nights, our electricity bill was €35 for 2 weeks which is not bad.
I highly recommend staying here, I also recommend booking an excursion to Panerea and Strombolio.
