we didn't meet Marco; he sent us in advance the code to access the apartment.This is quite convenient as we don't know exactly when we arrive. Marco was very flexible on the check-in/check-out hours; we really appreciated that. the apartment is really nice; the location is perfect to visit the center (just 5 min walk from the Piazza Maggiore and 10 min walk from the central station); the beds are comfortable in both bedrooms. AC in both bedrooms and the kitchen. the street is a little bit noisy in the evening, but I presume it's often the case in the center; there are small grocery stores,supermarket, restaurants and a pharmacy on the street.
I will definitely recommend this apartment for its location. Marvelous experience in Bologna!
