We stayed at this little studio in Florence for three days. It is only about 5 minutes' walking distance from the train station (which we greatly appreciated given our big backpacks) and about 10 minutes from the center of town. The studio is cute and original, especially its small upstairs sleeping area, although the steps that take you up can be a challenge to manage, especially at night. The place was easily big enough for the two of us for a few days. It had a TV (including DVD and VCR players) and its own WiFi router. Concerning the latter, there was a problem once (which turned out to be a problem of the provider company, rather than a problem of the device itself), but it was solved the same day, after we sent Luca an email. In general, Luca and his co-worker Alessandro were always on time and responded to our emails extremely quickly (usually within a few minutes), both before and during our stay. Thus, they were extremely reliable host.
One small problem we encountered was that the apartment had not been cleaned when we arrived; Alessandro apologized for this and organized the cleaning immediately; it was done within an hour.
Another thing to consider is that there is a night club just across the street and that the sound insulation of the apartment is not good enough to keep the noise out.
All in all, however, we would certainly recommend this place to other AirBnB users.
