The apartment is in an old building and it is lovely decorated, has a lot of charm and it was extremely clean. The location is just perfect, 5 min away from the bus station to the airport, 15 min away from the train station and right in between the old and new city so both are easily accessible by foot.
The only downside is the noise from the echo of the cars which pass the cobblestone street, so I would recommend earplugs if you are a light sleeper (closing the windows didn't help).
We've communicated great with Andrea (he proposed to leave our luggage several hours before check in, which was very nice) and overall we had a very pleasant stay in the apartment. Thank you, Andrea!
