Michele was super communicative - he accepted our last minute reservation in an hour notice, sent us local recommendations for the best places to eat and drink around, and responded to each and every question we had kindly within minutes.
The only unfortunate problem that he couldn't solve - and made us do an early check-out and forced us to find a more suitable place for the rest of our stay in Florence - is the weak Wi-Fi signal and no cellular reception in the apartment. The Wi-Fi is only 7Mb/384Kb and does not allow us to plan our stay, connect with our families, or do any sort of work from his place.
