I've stayed in many vacation rentals, and this was hands down the worst I've ever stayed in. The place was stinky and dirty. The owner only relies on guests to clean it. She has a company briefly check the property in between guests, but it's clear that nothing has had a proper clean in months. The floor was filthy, baseboards dirty, cupboards gross. It smelled terrible. But the worst of all was the 3mm thick mould on the bathroom ceiling. The owner said in response to a previous review that the mould had been "dealt with". It appears she thought spraying bleach on the mould was dealing with it? She is a terrible liar. I pushed her to properly deal with it, so she sent someone over to take a look. That person confirmed what we thought, which is that no ventilation in the apartment is functioning. I messaged her to report this to her, and after that I heard nothing from her. She left us in that putrid apartment with the mould getting visibly thicker by the day. All of this is unfortunate because the apartment itself is well laid out and comfortable. I would have gladly paid 100 euro more for the week if it was properly cleaned. The building is not great, it's in a party part of town full of young people, but that did not bother us. What bothered us was the filth. When she replies to this to say that all of these problems I identify have been dealt with, don't believe her. I told her outright that I was giving her the opportunity to get a good review instead of a 1 star review, and she did not take the opportunity.
