Mario, being a local and well connected, gives very good advice and recommendations. If you want to tour around the region (like Noto, Ragusa, Modica, etc. and you should) he is your man. Our highlight was when he took us to a mouth-watering local restaurant specialising in home cooked meals that is totally off the tourist map.
Mario's place is top notch. It's spacious and clean with designer fittings throughout. You have access to your own terrace and it's great for lovely views and sunsets. Located just a few minutes walk from Ortigia you must be reasonably agile, though, to climb up to his fourth storied apartment.
Not sure if this is a permanent feature but we were given access to Netflix and enjoyed cabled entertainment through the large curved screen tv.
