Nicola is a professional and experienced host. Our 4 day stay was perfect and he made us feel at home. I would totally recommend staying with him if you're coming to Florence/Tuscany. As we stayed 4 days, he gifted us a free tour to a nearby hillside town called Fiesole(just google it). It is a must go! The panoramic view of the entire Florence from up there was spectacular.
We also booked him for 3 day tours, to Chianti, Val D'ocia, and Cinque Terre and we loved every second of it. We were very comfortable with him and Spina and it felt like we're travelling with friends. Best host and best guide!!
