Nicola was very flexible, and even though we had forgotten to give him the time of our arrival to Florence he welcomed us almost as soon as we got there. He is a soon-to-be tour guide of the city, which you can tell by his will to show you the best that the city has to offer, and the city is absolutely lovely indeed. He took us to see several awesome places of Florence, which made our experience even better. He was always available to help us, and showed great generosity!
The room is big and clean, and the center is reached by bus from the apartment in 20 minutes or in 40 minutes by foot. We really have nothing negative to say about out experience with staying with Nicola, and can only recommend you to do the same! You will not regret having Nicola as your host.
