Flavio is a super nice and open guy. I really enjoyed staying at his place in bologna and every question i had, flavio was always super helpful and gave me great recommendations for the city.
His place is in a quiet area, just outside the city center. You have a cafe, small shops etc right outside the door and a bus stop, which brings you directly to the city within 20-30 Minutes. Be aware that the busses don‘t run super often in the evening (every 30 minutes) and most of the time, you need 2€ in cash for the ride.
I can definitely recommend staying with flavio.
