Andrea was the most kind host of my trip (and I visited 4 cities). He welcomed us right on time, explained everything and even left us a bottle of wine as a gift. The wifi works really well. The apartment is not the biggest, but it has an elevator, it is very clean and it has everything you need, specially if you don't intend to spend a lot of time there. It is also very central, you can walk to every place in Florence. I strongly recommend it.
