Great host, one of the best ! Friendly, open, nice, helpful.
Answers quickly. Provides a lot of useful info, tips for sightseeing in Bologna (he also gave us maps and told us about the history of the city). Helped us with transportation. We could call him with anything and he would be happy to help.
Everyday he offered us food for breakfast and pizza for dinner.
Luigi's place is 15 minutes walking to the city center, so great position as well. There's a store, bar and pharmacy right outside the house so that's great, too.
We would definitely come here again ! I recommend Luigi's place :)
