We loved staying at Luca's place. The apartament is perfect for 4 people, located right next to Piazza Maggiore, which is center of the city center in Bologna. The apartament was super clean, having two separate bathrooms was super convenient. The building is old and has a nice vibe. There's no AC, but each bedroom has a fan, which is enough to be comfortable enough. Luca is super responsive, he answered all my questions in no time, super helpful :) I recommend choosing this apartament for your Bologna stay!
