This apartment is the ideal base from which to explore Florence. It is close enough to all the major attractions (especially the Ponte Vecchio and Pitti Palace which are literally yards away) but it is even better placed to explore the beautiful Oltrarno area which is (in my opinion as an ex resident) the most interesting and authentic part of Florence. A few steps away is the beautiful Piazza della Passera that has everything you need to have a great time in Florence: a bar/coffe shop (Caffe degli Artigiani - The Artisans' cafe), a lovely gelateria and a great restaurant (Trattoria 4 Leoni)... A five minute walk from here is Piazza Santo Spirito which has lots more restaurants and great night life (my fave night spots are PopCafe and Volume.) This area is also great for wandering around and spotting all the artisan workshops where workers are busily making shoes, woodworks, sculptures and lots more. The owners are usually happy for you to pop your head in and have a look.
As for the apartment itself it has everything you need to spend a comfortable few days in Florence. The air conditioning is a real plus, especially in July when we visited. The central location means you can easily pop back to the cool flat when you are feeling hot and tired from all the exploring.
The host, Guido is friendly and accommodating. He was there to welcome us when we arrived and followed up regularly to check that everything was OK. There was a big storm on one of the nights we were there (which in Florence can be disruptive because of how ancient the city is) and Guido very kindly asked if everything was working OK, which it was!
One thing to note: In Florence they have had a crackdown on the tourist tax that each tourist is supposed to pay per night of their stay in the city. Airbnb has told hosts that it is their responsibility to collect this tax from guests (2.50 euro per person per night for up to 7 nights). After 7 nights you don't have to pay. Guido provided documentation to explain this, which I was able to read as I speak Italian. It's all perfectly legitimate, however, I think it should be made more clear on the listing so as to avoid any misunderstandings on arrival.
The only possible downside to this flat is that, due to it's central location, it is quite noisy at night - but nothing a good pair of earplugs can't fix!
I would highly recommend this property based on the comfort, the amazing location and the friendly and reliable host. Thanks, Guido!
