Me and 4 girlfriends stayed in Serena's apartment for 3 nights and had a wonderful stay. The apartment is spotless and has all the amenities you could need during your stay: fluffy towels, a great shower (well 2 even), fully equipped kitchen. The apartment is centrally located within 15 minutes walking from the Piazza Maggiore. The building itself is located just away from the street so it is nice and quiet at night. Serena was super welcoming and available to provide further information on anything we needed during our stay. She helped us find some really nice places to eat in Bologna which was greatly appreciated! I couldn't recommend this place more!
