Yes, this Airbnb isn't in a luxury room. It can be seen as "rustic style". But this Airbnb has a luxury host, Carlo. And this is the real point that you have to focus on ; if you want true encounters, sincerity, discover the typical Italian style, you are making the right choice. The beds were maybe not so big but it was enough and when you're tired you will sleep very well, trust me ;)
Carlo was so welcoming, he made breakfasts and gave us some bus tickets, perfect to begin a day in the wonderful day of Florence !
The localisation is maybe not in the center, but it's in a calm and peaceful place, next to a bus station and 10 minutes from a train station. And it's also realisable to reach the center by walk, so a good point also !
There were maybe some mosquitoes, but it's normal in this region. A little fault in contrast of what this room can offer to you, I highly recommend!!
