This flat is a gem, it's in the centre of Ortigia, easy to access and is as the photos show.
Chiara met us outside as agreed and spent quite a lot of time going through various aspects of island life: where to park and not to park, good places for breakfast and dinner, etc. She was super helpful and friendly :)
The wifi is very fast compared to most parts of Sicily - about 13mb/s download and about 9mb/s upload so was really useful.
All in all I would recommend this very highly: both the flat and the delightful island.
