TL;DR Overall, the place’s location is very convenient to go into Central London via Arnos Grove, indeed a quiet neighbourhood. Host and her son are friendly and welcoming. It’s a lovely place for short stay as long as you don’t need to use their washer and are not immunocompromised or needs shielding.
Duvet cover and bedsheet were clean and newly put on but the actual pillows and duvet smell like sweat, but you can get used to it and get over it.
There was black mildew on the washing machine door with days-old wash inside when I arrived on 2/7 Saturday, the host cleaned it on Monday after she came back, yet the machine still looks like it has never seen a washing machine cleaner. I used at least 8 dettol wipes to clean the lint/mildew/god knows what gunk at the rubber edge and mildew marks remains on the rubber bit. (Host claimed it was normal wear and tear, it’s not, my home’s washer in much more humid climate never had those marks).
And yes, host went to music festivals in Glastonbury the weekend I arrived, and according to her, someone she met on Saturday later tested positive. I booked my stay months ahead (when Airbnb Covid policy still applied) and I was not told about her travel plan. I was only notified on Tuesday night someone in her circle tested positive as I started to have COVID symptoms so as she did. None of my close associates (close contact without masks) for the whole week prior to meeting her(including her son) had Covid, and I’ve worn masks as normal practices, yet she claimed I was the one that gave her the virus cause I had my usual allergy cough when I met her.
Airbnb’s Covid policy said host shouldn’t host or enter their listing or interact with guests if they know they have sustained contact with someone that confirmed or suspected to be infected with COVID-19 within the last 14 days, but it’s only a guideline and there’s no law mandate anymore so she’s not “breaking any law”. But it’s still a shitty thing to do and I lost a week of my time-sensitive laboratory work that I can never get back. I still have brain fog and continuous coughs til this day.

The night she tried to gaslight me into thinking I was the spreader, she came into my room without asking for permission(or at least I didn’t hear her and agreed for her to come inside) and she requested me to confide into her why I was crying at night when I apologised and said I’ll keep it down. It was all empathetic until she went on to tell me that“a lot of people are getting sick now, it just happens, and it doesn’t matter how anymore, we just have to accept sometimes bad things happen, and there are things that we can’t control, and it’s important to know what we can and what we can’t” to minimise her responsibility, then proceeded to say she also suffered financial loss as well cause she couldn’t work or attend another music festival the next weekend. And she went on about how she believed she got it from me and suggested to me to not worry about trying to move out and should focus on recovering from Covid, then gave me a lecture on old wives’ tale that she believes in that is crucial to recovery (sunlight, fresh air, micronutrient intake) which I don’t deny those are important to one’s health but it feels manipulative to have her told me that when I was sick in her listing very likely from her, and for her to tell me not to worry feels wrong. And then she went on to be friendly and polite again like she had never said those things to me when I was emotionally distraught.
Maybe in a different timeline where we don’t have the pandemic I would have had a better time with her, sadly it wasn’t.
