Tomasso was the best host we've had via Airbnb so far. The first night he cooked us a meal and recommended what we should do whilst in Florence, which we did and were not let down.
After the first night, we did not see Tomasso again as he had to leave for the weekend but his place was lovely and we had everything we needed.
The place itself is a little bit out of the main town but it's very walkable and we actually liked the fact it wasn't in the touristy area as the place was quiet at night. The room is spacious, the bathroom is clean with a good shower. He has good kitchen facilities and a nice living room. There's also a balcony, which is particularly nice in the evenings.
I thoroughly recommend staying with Tomasso if you get the chance.
I would say one thing- Tomasso has a limit on his internet so if you stream a film, you won't have internet for the rest of the day. This is not a negative as its not essential but we didn't know this before and learned the hard way when we needed the internet for finding directions. As I say, not a problem but just worth knowing. If you don't stream anything, you're absolutely fine.
