The flat was clean, spacious and tidy. Our hosts had kindly put milk in the fridge and cakes for our breakfast. The area was residential and in a quiet location a short 10 mins walk to Ortigia or 20 mins to the Ancient Greek archaeological park, so we were out most of the time. Parking right outside was never a problem. We had excellent food at Monzú and Ristorante Retroscena was even better! The best gelato was at Gelateria Bianca... coming from Bologna that's important! During the booking nothing was a problem and they kindly arranged for a travel cot for us. We really enjoyed ourselves.
There were a few very minor issues that could do with sorting out, the loo seat could be fixed on properly, the first cupboard we tried to open in the kitchen the door fell off and landed on my wife's toes - ouch, the batteries were flat in the TV remote and their were a few scruffy patches of paint that had fallen off despite the whole place looking like it was fairly recently renovated. More worrying were the bare electricity cables hanging out of the walls where lights etc must have been planned. Not very safe! The single bathroom wasn't ideal for us with young kids as there wasn't a separate loo. The third bedroom was the mezzanine landing so we had to walk past someone and down squeaky stairs.
On the whole it was a lovely apartment so I'd certainly recommend for one or two couples, but three would be too much as the third would get no privacy.
