Luciano was a very nice host with lots of great advice! He is quite welcoming.
The private room is as depicted, comfortable bed, fresh sheets, and fresh towels. It's a bus ride to the main square, but we walked wherever we went. Walking takes about 30-35 mins. If the weather is nice we recommend the walk, it's on the river with little places to stop for a bite to eat. We even walked at night and felt totally comfortable doing so.
Overall, we definitely recommend Lucian's place. It was perfect for our short two day trip to Florence.
