We contacted Marcelo as we were driving toward Siracusa, giving him only an hour's notice before our arrival. Marcelo was easy to reach and communicated very well. As Airbnb hosts go, he is extremely friendly and helpful. The parking garage on the island was out of use due to flooding when we arrived and Marcelo was able to direct us to alternative parking.
The apartment was just as pictured and advertised. Very new and clean, with all amenities. It was quiet and comfortable. We were able to walk easily to all the sights during our stay.
