I would highly recommend Nicola to anyone considering a place to stay in Florence. We stayed with him for two nights while visiting, and the whole time he was a fantastic host. The place was very clean and comfortable, and if we had any questions, Nicola was quick to answer to the best of his ability and would even give recommendations. While we were there, he gave us a brief tour, and when the city bus time tables changed, he even drove us to the train station so we wouldn't miss our train. Overall, it was a very positive experience staying with Nicola. Not to mention, his dog is pretty adorable.
