We've stayed at Francesco's appartment for 5 days and it was perfect. We were welcomed by his daughter and she showed us around the appartment and explained everything we needed to know and there were even some homemade cakes! The appartment has everything you need, from a coffee machine till a washer and dryer, great shower and an ac. Location was also very good. A few minutes walk to Piazza Maggiore. I definately would stay here again when I'm in Bologna!
