we stayed 14 days at lambertos house. one of the best thing is definitly the roof top terrace. we had almost every evening our dinner up there. as well the site of the Appartement is perfect. absolutly in the Center, but very quite (if the crazy old lady and her dog don't yell). the free parking area outside of ortigia is close, the market, the supermarket and a lot of coffees, Restaurants and gelateria are close.
we liked it a lot to stay at this Appartement and can recommend it.
