The apartment is as good as it looks like in the pictures. In fact, the views from the tower are even more impressive. There’s air conditioning in each room so heat during the hottest hours of the day in August was not a problem at all.
Be aware that it’s a 4th/5th floor without elevator - naturally as it’s in the middle of the old town - and that you’ll need a phone that can make (free) calls in Italy to enter the building - something very basic but still good to be aware of.
I definitely recommend the apartment and would gladly go back when I visit Bologna again.
