We had a great time at Marco's apartment. He is an awesome host. He did so many great things, like meeting us at the station, leaving some wine in the room for us, and helping us organise an excellent tour guide when we got stuck.
The apartment is in a perfect location. It's close to the bus and train station, a large supermarket, and is an easy walk to Ortigia. Definitely recommend Lilia's house for a weekend in Syracuse.
