My husband and I had a lovely stay in Carlo's apartment. Took a taxi from Bologna Centrale (under 10 euros) and had a very nice welcome from Sergio. Apartment is in a beautiful locked courtyard and felt very safe. Check in and check out was very easy and Sergio was nice enough to call us a taxi upon leaving. Close to everything. We walked everywhere including into the historic center. Thank you Sergio and Carlo! Bologna gave us wonderful memories and if we ever come back would love to stay at your apartment again!
