The flat is beautiful and very practical, in the very heart of Florence, quite literally in front of the Duomo. From the apartment everything is reachable on foot and quite close, there's a pasticieria right down the flat for breakfast and a tiny supermarket one minute away.
Ciro welcomed us himself. He is very nice and helpful, and available for advice on the sightseeing part!
Only downer : the noise. If you're sensible to it, you need to get ear plugs, the centre of town is very lively at night!
