Vanni's place is extremely quirky and everything is unique in his apartment, which made my stay a bit more interesting than other places I looked at for Florence. Not a fault of Vanni's, but currently there is some tram line construction happening on nearby roads, meaning that the buses were on diversion routes and therefore it wasn't as easy to reach the centre of town as easily as I thought, but coming back at the end of the day was fine (it was a bit too far to walk everyday especially in the summer heat). The only other thing was that as a non smoker I was slightly put off by the strong smell of smoke in the apartment so I mainly stayed in my own room and kept the door shut. If you're looking for a unique place to stay I would recommend Vanni's place, he is very friendly and welcoming and I had a nice time staying there.
