Martina was a great host and the flat is superb, centrally located and genuine. On all Airbnb's criteria (cleanliness, accuracy, etc.) this would have been a five star stay, but since we were a family with two small kids, this was not the most suitable option for our needs.
The kitchen and bathroom are quite compact, and apart from the (otherwise amazing) terrace there's not a common area and/or a living room (just two bedrooms and a corridor). If you are traveling solo or just as a couple, this will not bee an issue. But once you put two kids to bed, there's no more space to just chill after the day. However this is more like a mismatch between the flat and our needs – I still very much would recommend the flat for travelers without kids.
Another thing worth highlighting for people traveling by (rental) cars. The flat is located within the restricted traffic area (ZTL), but just as Martina told us, there was a street (Via Zanolini) with reasonably priced (€7.50/day or €1.50/hour) public parking within walking distance. We stayed a week and did some small day trips every other day, and upon returning could always find at least one free spot. It takes about 5 minutes by foot to reach the flat, so I would recommend to try the public one first before buying a spot in a private garage (rates are at least double as high).
All in all, despite some space related issues with the flat, we really much enjoyed our stay in Bologna. It's an easy city to get around (even with kids) full of amazing restaurants, bars, cafés and market halls. Martina was easy to reach, she provided us with recommendations and insider tips, and ensured we had a great week in Bologna.
Thank you for everything :)
