We loved Valentina's place!
My wife and I were visiting Firenze for a week, while working remotely and Valentina's was the perfect place! The house is big. The Kitchen is so well equipped. It has it all. The place was super clean.
We both worked remotely, and the wifi was perfect, we didn't have any trouble with it.
The apartment's location is really good. You may have doubts because it is not in the city center, but you have a Tram Station right in front of the house, so going to the center is easy and may take like 15 minutes. You also have a bus line going to the center like a block away. And you don't have all the turist and stress vibe of the center. The neighborhood is really quiet. And you have a huge Supermarket really close ( Take the tram, it is only one station). You have just a few restaurants, but those are really good. Villa Costanza bus station is like 5 minutes away by Tram.
Valentina was always super fast to respond any question. We felt super comfortable there, and we would like to go back once we visit Firenze again!
