Outstanding flat right in the center of Bologna, exactly as advertised. The air conditioning worked very well, even with temperatures pushing 90. Same for the water heater and kitchen appliances.
Barbara is the best AirBnb host I've ever had. She met us at the flat and gave us a comprehensive overview of the town, including some truly terrific restaurants. She even lent us some cash for the taxi fare when our driver's credit card machine wouldn't work! And she arranged a taxi when we left.
We will absolutely return the next time we are in Bologna (hopefully soon).
