We had an amazing 4-day stay at Jacopo's place. The apartment is in an ideal, quiet location, great for exploring not only Ortigia, but the wider region around Syracuse, too.
The apartment is cozy and clean, with everything you need for a short stay. On a 2-minute walk radius, there are wonderful pastry and coffee shops, restaurants, and several scooter, bike and boat rentals.
The bus (and train) station is only a 15-minute walk away.
Jacopo was super responsive and we'd recommend his place to anyone.
