The neighborhood is great. Full city center a few steps from all the major monuments of the city. Restaurants, cafe, pharmacy, supermarket, everything round the corner.
The apartment is beautiful and the terrace breathtaking! All the needed stairs everyday were rewarded by the most amazing view over the duomo. I'm originally from Florence, but having the opportunity to have that kind of view everyday was a great gift. The view from the windows of the living room is like having amazing paintings.
The apartment is well furnished with everything you may need. We managed to do groceries at the Mercato Centrale and cook ourselves a great dinner and eat on the terrace.
The air conditioning (needed in the summer) is very efficient.
The apartment is well soundproofed.
We loved the Lightning with led lights.
Bathrooms were spotless and practical and the shower had good pressure.
Wifi was not very fast but reliable and always on.
The matress bed in the main bedroom was a bit too soft for us, but I guess it's a matter of taste and anyway the one in the second bedroom was ok.

Overall a great experience. Should I need to rent another time an apartment in Florence I will for sure consider it. And I will recommend it to anyone.
