Gianmarco is a great host, he was reactive and welcomed us late despite some change in our time scheduling.
His appartment is very well located in the city center, and benefits of a great view of the Duomo. 5 to 15 min walk from almost everyhting (train station included).
Flat and rooms are correct for 2 persons and big enough. Bathroom are clean.
We enjoy a lot Florence thanks to Gianmarco and its useful guide.
Cheers,
Thomas
