We've stayed for one night at Giovanni's place during our trip around Sicily. The apartment itself is very nice, with all necessities provided, expect for wi-fi, but it was not a problem for us. It has a large private terrace with a bit of a sea view, large living room and bedroom. Historical center is about 10 minutes away maximum and you can easily walk to most Marsala's interesting places. Parking is free on the street near the apartment which is also a big plus. We had a really good time here, recommended.
