Marco was the perfect host! He was very friendly, welcoming and helpful in everything we needed. His flat is also very nice and clean and one can find everything that is needed.. and it's just a 10min walk to the city center, the duomo, etc.! We didn't buy any bustickets at all for 3 days because the location was so perfect.
Marco was also very trustful. He was not in the flat the last two days we stayed there but still he trusted us that we take care of everything.
All in all it was the perfect accommodation for me and my boyfriend in Florence! Thanks again Marco :)
