Carlo's flat in Bologna is seriously the coolest place to stay in the city! There are artifacts under the floor and there is an ancient well in the flat. It is very, very neat and we loved staying there! It's conveniently located very close to the city center, but not right in the middle, so it's just perfect. There is a kitchen where one can cook, if you like and the flat is generally very tidy and clean. Carlo left all sorts of brochures and guidebooks for us to peruse, which was so kind. He even stayed up beyond check in time as our flight was late arriving and was happy to accommodate our bringing our toddler along. There is a great place directly across the street for pastries and coffee in the morning, and a short walk down the street on the same side is an AMAZING gelateria! I highly recommend staying at Carlo's flat if ever you visit Bologna!
