Claudio accepted my very last-minute request made the night before I was to arrive, and I was so relieved! It was a great room, airy, spacious with good natural light. The private bathroom was a modern one and a good change from some of the hotel's I've stayed in Italy.
I didn't see Claudio much during my stay but he was there to receive me, and he was funny the couple of times we talked. Very smiley and friendly, he immediately showed me around the house when I arrived and flipped through a guidebook to brief me about the area.
I messaged him via airbnb a couple of times during my stay for some help and he was very quick to respond.
The apartment is just a short walk to the Duomo and Ponte Vecchio. It's in the heart of the city, really. There's also a supermarket nearby and a few eateries around.
A great place to stay, especially given how affordable it was. Recommended!
