The stay at Serena's place was really fantastic. Bologna is known for being a fat city, and this apartment is right at the crossing with amazing bars and restaurants. The main shopping center of the street is nearby and the Quadrilatero is to a 5 minutes stroll. Serena was a great host, she welcomed us warmly (not only because the temperature was high) and the apartment was everything we needed to have fun in this alternative city. Definitely recommend!
