I've stayed in a number of Airbnbs, and as a host, Andrea is probably one of the best!
Communication was great, his responses were very prompt. He gave me good instructions to the apartment and met me at the bus stop. He then showed me around the apartment and even spent time telling me where to eat and what gelaterria was the best in Bologna!
The apartment itself is quite spacious, light and airy. It's on the top floor and is about a 10 min walk to the city ring (the ring road around the city) and about 25mins to the city centre. Bologna is a cycle friendly city, so I would suggest to hire a bicycle (probably a 10min cycle to the city centre).
It's got double shutters in the bedroom, as I have bionic hearing, I was worried about the sun/traffic in the morning. But I slept like a baby and didn't hear a thing! The kitchen is fully equipped and Andrea provided me with some croissants, jam and coffee for breakfast - which was a nice touch...
The shower had good pressure, and the bathroom was clean - there was even a hair dryer!
My flight was an early one, Andrea kindly also booked my taxi for me.

I would definitely recommend staying at Andrea's place-awesome host and great apartment!!!
