My stay at Sandra's apartment was great. It is definitely big enough for at least 3 people. Sandra puts much thought in making her guests as comfortable as she can with breakfast foods provided and setting up a clean and comfortable place. The location is perfect as its so close to the main square in bologna and just outside the apt are many restaurants and bars, and very close walk to the train station. A couple of slight negatives: the wifi signal in the apt was rather weak. There are at least 4 flights of stairs to head up to the apt so beware if you have big luggages but it wasn't a problem as Sandra was very helpful to help me when I arrived. As with many European buildings, the apt walls are super thin so in the night, I could hear next door coming home late and talking, hopefully you won't experience that when u stay there! I would still highly recommend Sandra's place.
