We spent 10 great days in Valentina's apartment in Ortygia.
First of all the appartment is located in one of the nicest alleys in the heart of Ortygia, lined with planters and close to the plaza del Duomo. Around the corner are 2 small supermarkets, a take-away place for pizza, calzones and arancini in the evening and sweet pastry in the morning. On the other end of the street in the direction of the plaza del Duomo is a bakery with excellent espresso to lighten up the start of the day. The daily fish- and food-market is also in walking distance. For the rest, Ortygia itself is located well to explore the west side of Sicily.
Secondly, the appartment has a nice, modern design interior with the sleeping matrass being located on a loft which can be reached by a design stair, which is not fit for people that have difficulty walking. Light is coming in only from the front and when it is sunny, you can open the double doors and sit in the street, where the sun will be shining through for 2 hours in the course of the afternoon. In summer it will be cool inside, but we were in Ortygia in March, so we needed some warming which is provided by a butagazz heater. There is wifi, albeit slow and with moderate reception.
Third, Valentina is an excellent hostess, who responded quickly to all our needs and questions.
I would certainly recommend staying here when you would like to have a break in Sicily.
