I stayed for 3 nights at Tommaso's apartment. The apartment was clean and neat. In the perfect location, 5 minutes from the main train station and in walking distance to all the places you would want to visit but on a quieter street to others that surround the area. WiFi was spotty at times, but not an issue as you could easily find WiFi nearby.
Tommaso was very helpful and communicative. He provided us with tips on where to go and answered all of our questions. The bottle of wine was a lovely touch.
Tip for those flying into the Florence airport, the bus shuttle is 6€ a person and takes you directly from the airport to the main train station near the apartment. Highly recommend this travel route as the taxi line was around the corner and would take longer to get than the bus.
