The apartment is exactly as is shown in the photos. One thing we loved about it is that it has that old Bologna charm in its architecture. The bathroom is pretty big, and the kitchen is very well equipped. The beds are comfy and the entire place is very well air-conditioned. Be prepared to climb some stairs though. We didn't mind burning off a few calories after all the pasta and panini we'd consumed during the day though :)
Best part is its location. It's about a 15min walk from the main piazza and the city centre, and just a short bus ride (under 5min) if you don't feel like walking. It's also close to a lot of shops, salumerias and bars.
Gianmaria is a great host - he explained everything we needed to do to arrive safely at the apartment, and check in was really smooth.
Overall, a great accommodation!
