Rocco is an amazing host with quick replies to messages and questions. He combines the friendliness and politeness one is looking for in a host. Further, his flat is completly up-to-date, clean, easy to reach, and comfortable. The direct surrounding of the flat is not the nicest but functional. There is a parking space right in front of the flat which was the most important for my trip.
Further, Rocco takes care about you with additional information such as restaurant and sight-seeing recommendations.
If I have the time or need to go back to Bologna, I would be happy to stay in his flat again.
