We have stayed in a few dozen AirBnB's over the years, and Emanuela & Peppe's apartment was one of the most charming.
The location was perfect (though it got a bit noisy on Thursday and Friday night with local entertainment right outside our window), it was clean, attractive, spacious, well-appointed, and the furniture was more comfortable than the standard AirBnB Ikea.
We will plan to stay here again on our next visit to Ortigia.
