Positive review, read the whole thing please :)
There was an issue with the location of the apartment on the map (quite far away from the correct location, even though the written street address was correct), but I would like to highlight that Manuela, the host, was very helpful and did her best to resolve the situation. (We then received a reimbursement from AirBnB since it was a technical issue from their side, and it now seems to be fixed.)
The flat itself is very comfortable, quiet and well-equipped (and there's even an AC). It's small, but we did not find that to be an issue.
