We had a very good time in Valentina's apartment. Her father was very nice and helpful. The apartment was renovated with a lot of good taste and attention to details. The location was perfect, right in the city center, 3 minutes from the sea, with all the bars and restaurants around. The steet is probably the greenest in the whole of Ortigia, with a lot of beautiful flower pots.
We went in february and it was quite cold, even with the electric gas stove. The pictures were a bit misleading, at least for us. There wasn't much light in the apartment, but probably this is a plus during the hot summer.
We would definitely recommend the appartment.
