The apartment is in a basement with pretty much no natural light and has major issues with mould, since all the rain accumulates in a tiny patio. Furniture is smelly. It’s also noisy as you can hear pretty much everything that is going on upstairs, where the owners live. The good things are the location and decent amount of artificial light.
There are also hidden (major) health issues like rusted (few months old rust) kitchenware to be aware of – be careful e.g. before serving a coffee from the French press (I wish I could attach pictures). Hair from previous guests are to be found on cushions / sheets.
Perhaps most importantly, you need to be aware that this may NOT be a relaxing stay for you. The owners have a guidebook and anything THEY deem claimable will be claimed and much more (I have received a £640 claim after leaving the flat including bill for that few months old rusted kitchenware. What audacity to do that!).
If you damage a basic guidebook – it’s £200 (this is what alerted me on potential abusive owner behaviour). The list goes on. In the end the flat needs to be refurbished from time to time and you may end up picking up the bill (including replacing those smelly drawers) if you’re not careful and don’t document things on EVERY occasion.
I am not a conflictual person and wanted to avoid the confrontation with the owners and this review but the unethical behavior and the £640 claim forced me to react. I will leave some aspects of the conflict aside to remain objective and so as this review provides value and serves as warning for potential clients.

That said, it is to note that the owners record your movements on CCTV and will threaten to use footage against you (I am investigating with relevant authorities how this is supposed to comply with GDPR).
Since (at least one) of the owners has the habit of attacking people on personal grounds, I will pre-empt this by saying that they recorded me illegally and their accusations are unfounded. But you probably don’t need to know the details of the issues (that’s for Airbnb to resolve).
Know though that you are being recorded and I suspect everything you say is also heard upstairs.
So yes, to summarise - a very stressful stay while being recorded even when dropping a PCR sample.
