The apartment is central, in one of the most lively streets of the city. There are plenty of bars and cafeterias around, and most of the sightseeing places are in walking distance.
Unfortunately the apartment has some ventilation issues and the air gets damp quickly after taking showers, resulting in mold-smelling bedsheets and mold on top of the shower. I would say the apartment is clean otherwise.
The hosts have been very kind, and the self check-in procedure is really straightforward.
