This had the potential to be a perfect stay, but sadly the hosts ruined it, making it deeply unpleasant. The location, security and cleanliness of the property were perfect. Comfy bed too. However, whilst the property was marketed as "Chic Minimal Studio with Views over Battersea Park", upon arrival I found 100% of the view to be covered by scaffolding, leaving zero view and very limited natural light. In addition, I had made it clear to the hosts in advance that I would be using the apartment to quarantine and would not be allowed to leave, so would be making good use of the balcony - the only source of fresh air into the apartment, with there being no other opening windows. Upon arrival, I found the balcony door would not open - like it was broken in some way. I immediately reported this to the host (via their management company, Houst) and after a period of 48h of chasing up to get to a resolution, it became clear that the host was refusing to take any action to resolve the issue and would instead leave me with no access to fresh air for over a week. The management company did tell me that they had a handyman they could send over within a few hours if the host gave the green light, but that never came. He did make one 'helpful' suggestion - that if I wanted to smoke, I could do so under the kitchen cooker extractor fan. Not a great or pleasant idea in a studio apartment with a smoke detector in the middle of the room. I plead for him to reconsider but was simply given a 'no' by Houst so I had no other choice than to contact Airbnb. Airbnb then tried contacting the host and after having no success themselves, they unilaterally processed a partial refund (which I'm sure cost the host more than the repair work would have anyway). I was so relieved when I was finally able to leave the apartment after completing quarantine, which is so disappointing because it is a lovely flat but the host totally ruined it.
