The apartment is in a excellent condition, it's super clean and super comfortable. I would even say that it's way better than many hotels rooms that I've been in Bologna. It's visible how much effort and dedication the hosts put on this apartment to make it as great as it is.
If you are coming to Bologna to enjoy the city center and the night life, the location is just perfect: It's just a few steps from the Due Torri and Piazza Maggiore. It's also surrounded by many bars and restaurants. If you don't carry much luggage, it's also possible to walk from the train station to the apartment, but buses are available as well (but it's way more fun to get lost in the historical narrow streets of Bologna).
Regarding the hosts, they were very responsive through messages. Elena also showed us the whole apartment and explained very well how everything works. They also prepared a list of recommended places to go and a list of emergency numbers and etc which we highly appreciated.
In summary, just perfect :)
