My fiancee and I spent five days in Elena's apartment, and it made our stay in Bologna very special. It is clear that a lot of time and attention was spent to ensure that the apartment is comfortable, clean, and that your time in Bologna is wonderful.
Elena is a rare host. She took time to meet with us, share suggestions for places to visit or where to eat ('this place for that dish but not that one,' 'this other place for a drink but not food' kind of recommendations that are very valuable). The short walk from the train station (or easy bus ride), the easy access to the main tourist areas of Bologna while still being outside of them, and convenience of seeing the west side of the city also make this place a gem.
Our entire stay felt warm and welcoming. When we finally checked out, we had to rush to the train station and did not have a chance to say goodbye to Elena. The fact that we did not know her a few days before, but felt truly sad to not thank her face-to-face, should tell you all you need to know. She is a wonderful person, and this is a great apartment from which you can experience Bologna.
Just book it! Trust me!
