In was a holiday trip in Florence. We arrived to the city late, but manager of the hostel was waiting for us. First night we had in a tent in the garden, which about I was not that happy, but on the morning we got a nice double room for the same price as a tent, where we were staying with a friend for a couple days more. The stuff is very friendly, and helpful - showed us around - we went together to Villa Montalvo and on the other day to amazing pizzeria in Vernio (40 km north of Florence).
Room was nice and clean, internet connection was good too. There are club just in a few minutes walk and a nice pizzeria.
The hostel is placed close to airport, and it's just 20 min by bus from train station.
