Massimo's place was very clean and stylish. The apartment is not big but it is very efficiently laid out so there was enough space for our suitcases. The hosts were very responsive and check in was super easy. They also provided some great restaurant recommendations with lots of guidance and considerations, which is much appreciated as we were visiting Bologna for the food.
Keep in mind the apartment is on the 3rd floor by American measures (2nd floor in Europe as the first floor is 0) so it was a bit of a hassle to bring our baggage up. Also if you are staying during the summer, the A/C is not super strong so if you are sensitive to heat while sleeping this could be an issue. All in all, it was a pleasant stay in a convenient location, with great hosts.
