Concetta's apartment's location is superb, close to everything you would possibly want to visit in Ortigia. If you want to visit Siracusa center or the archaeologic park you can take the bus right in front of the house. What is best, it is by a solarium point which you can swim or sunbathe. Concetta is the nicest host, she treats you as you were her guest rather than a customer. I can simply say she took really good care of us.
The house is an old one, if you are waiting for a smooth hotel-like experience it might not be the right choice for you. But if you would like to enjoy Ortigia in a nostalgic house in a very good location then you will be really happy in Concetta's apartment, it is great value for money.
