This was a very nice stay in Bologna. There were 4 of us and the apartment suited our needs perfectly.
The location is exactly as described, it is in a quiet , safe , family friendly area with VERY secure parking. It is 200 m from the city walls and 15 mins walk into the centre if you walk slowly ( 20 mins on the way back if you drink wine )
The apartment has all amenities required, not air con in all rooms but a small mobile unit in the kitchen and fans in the bedrooms. The kitchen / lounge is small , but again , we are in Bologna to be out and about and the bedrooms are more than big enough ( as is the shower room and toilet ) so the living area is just a pit stop for breakfast then you are out for the sights and sounds of a vibrant city.
The beds are comfortable and everywhere is spotlessly clean.
Best of all , Barbara is always in contact for any question you have. In fact she is probably the fastest we know to reply to a question.
I would not hesitate to recommend both the apartment and Barbara herself too you.
