The location is arguably perfect - we walked all over Ortigia and can't imagine a better place to say. It has water views but is still on a super fun, bustling street with cool restaurants and shops below. We were traveling with two small children and I think this was our favorite stay of our trip - largely because of the location and walkability of Ortigia, but also because of Massimo's wonderful hospitality in making the apartment incredibly kid-friendly (e.g., baby gates, snacks, pack n' play, toys, diapers, a baby bath etc.).
The apartment is simple, but very clean and the views from the mini-balconies are wonderful. Only consideration is there is a lot of street noise - as the street below is bustling - but our kids slept right through it with a sound machine, and it didn't bother us. Would absolutely come back.
