Serena's was the perfect choice for my first visit to Bologna! Every small item makes her apartment a fascinating place. +her strudel is delicious. Her location is the best: directly across small street from Mercato del Erbe (daytime vegtable market springs to life until 11pm or later because its several restaurants/barsare filled with locals socializing .. especially on street below (I enjoy the night noise of humans enjoying themselves). Historical Bologna is very walkable, but Serena's location at the mercato enables (after daylong walkabouts fatigue) saving the day's last meal & wine for only 15m from a comfy bed!
