Great apartment, charming space, and very convenient location just a couple of blocks from the bridge over to Ortigia (but just outside the ZTL so we could park our rental car with no restrictions).
Mario was an excellent host also, with very helpful sight-seeing advice etc.
Our only disppointment was that during out stay we failed to find anywhere better to eat than the place that Mario took us to for lunch when we arrived, which was excellent!
We should have followed his advice more closely...
