The flat is a bit far from the city centre (1h walking) but the public transportation is good. This also includes regional trains (sometimes it's faster to get around Bologna Centrale) and night buses (they go once per hour and the bus stop is 5 minutes walk from the flat).
The flat itself was spacious enough, clean and a bit qaint. It has all the things we needed: washing machine, dishwasher, microwave, iron and ironing board, etc.
Monica was answering quickly which was a great help (e.g. I didn't know how to turn on the washing machine :) ).
