It's hard to write this review because I don't know whether to spend all of my praise on the apartment or on the host, Caterina. :)
Caterina is a magnificent host! She went out of her way to be very, very, helpful. Her communication response was amazingly fast and she tried to help us every chance she could. She even contacted us a few times during our stay to make sure everything was going well and to ask if we had any questions! Amazing!! She sat down with us and showed us special places on the map and gave us a lot of dinner suggestions.
Likewise, her apartment is over-the-top good! It's spacious, VERY nicely decorated and makes you feel like you're "at home". It's well located for doing or going anywhere in town. It's a short walk from the train station and a shorter walk to the city centre. The apartment was absolutely sparkling clean, with a lot of extra amenities to make things nicer. The AC and wifi are good; the lift in the building is reasonably fast.
On our next trip to Bologna, we will DEFINITELY stay here again!
