We faced 4 issues during our stay in the apartment that made our stay not as pleasant as we would have wished:
1) The quality of the sofa-bed is terrible, definitely not acceptable from our point of view to rent the apartment for 3 persons with the current sofa-bed. It is the final backbreaker for any person staying for more than 1 night.
2) The overall hygiene of the building was very bad, strong smell of pee from the moment you crossed the street door until the moment you get inside the apartment.
3) The overall hygiene of the apartment was just ok, but the hygiene of the towels and bedsheets was not up to what we believe are the minimum Airbnb standards
4) We did not appreciate the fact that the cleaning staff entered the apartment while our belongings were there without previous notice nor confirmation from our side (entered at 12:01 without absolute no flexibility on the check-out time).
