Silvia's apartment is in a very good location. From here you can walk to both Ortigian and archaeological sites.
The apartment is a clean and lovely penthouse and can be reached by elevator. There are hardly any views, but the city is full of sights.
The apartment has everything you need for a longer stay. There was much fruits and quite a lot everythig you need for cooking.
There are good transport links to nearby cities such as Noto and to Catania airport as well. I recommend
