My wife and I stayed at Francesco's apartment in Florence in September 2021 and the following were our thoughts regarding our stay.
Pros:
-Excellent location! Short walking distance to all the best sights and restaurants throughout the city. Parking garage very close to the apartment for our rental car.
-Very responsive host, check-in was easy and Francesco provided plenty of great recommendations for our stay.
-Rooftop terrace with incredible views (amazing view of the Duomo)!
-Spacious apartment
-Very comfortable bed
Cons:
-Wifi did not work. Francesco tried to have this fixed during our stay but despite this, the signal was still too weak to even browse the internet (unless you were standing right next to the front door).
-Tub does not work.
-4 flights of stairs to get up to the apartment, no elevator so be prepared! Worth it for the rooftop terrace but bear in mind if you have a lot of luggage.
-Small A/C unit for the bedroom only, rest of the apartment does not have A/C.
If the wifi was fixed and you don't care about having a tub in the apartment, this is a great place to stay and would definitely recommend it, especially since you will probably be out of the apartment for the most part sightseeing around the city.
