Andrea was a fantastic host and couldn't have been more attentive to detail (a bottle of wine even tempted me on arrival), accommodating when I asked to check out late on my last day, and quick to respond.
The flat itself is beautiful, full of period features, very clean, and a stone's throw away from the Duomo and Santa Croce. Only slight downside was that there was little natural light inside, but there are plenty of light fittings so that this wasn't really a problem.
Would definitely try to stay here again if/when I return to Florence. Thank you, Andrea!
