Excellent! I stayed in the apartment for three weeks. The apartment is in the centre of Bologna with lots of shops nearby. Despite being very central the apartment is on a side street and is quite quiet. The apartment is very modern and clean and has all the amenities you will need - extra fast wifi, washing machine, large dishwasher, fridge and freezer, iron and hair dryer. The cleaner also came once a week and provided new towels which was a nice touch.
I also loved the large glass windows, one of which opens like a door. The large TV is also a great bonus.
Daria was also always on hand if you have any problems at all. She is very friendly and resolved any queries/issues very promptly.
I would highly recommend this apartment.
