We visited Bologna for a conference and didn't know what to expect. The town, although rather small held a lot of unexpected and pleasant surprises much to our delight. The apartment itself was very nice, situated in the center of town with quick and easy access to a lot of good restaurants and tourist sites nearby. If you plan on visiting Bologna, this is THE place to stay.
Federico was very communicative and helped answer all our questions. Likewise, his friend and assistant Patrizio came to welcome us and even recommended some nice places to eat.
Pro tip: When you arrive at the airport you can ask the taxi driver to take you to the Apple store in the center of town because the apartment is in the building next to it.
