Gabriele's place is just perfect - amazing views, great space and a brilliant central location. The street and Piazza Verdi get pretty busy on a Saturday night (which was great fun), but you can hardly hear it from the apartment.
Gabriele himself I think is even more impressive, he made us feel incredibly welcome, had some excellent recommendations for food and things to do in Bologna and to top it off, he's a complete legend.
The best experience I've had so far on Airbnb without question.
