Silvia's place is great - very near the main areas of the old town, just around the corner from one of the best Ice Cream shops and loads of great restaurants / street food.
The flat is small and tidy, with a lovely little terrace area (sadly it rained while we were there) and a basic kitchen. There's also a selection of tea/coffee/beer/wine you can purchase for a small extra price.
Silvia met us on arrival and was very helpful and easy to contact.
