@Ali11529 Before Coronavirus (BC), I would've said that renting a private room in a shared home was a great arrangement for backpackers, tourists, and work travelers. You're out of the house and busy during most of the day, so why spend the extra money on a place you're mostly just going to sleep and shower when you can instead use it to give yourself a bigger budget for the things you really love? As a guest, I'd much rather spend the extra money splashing out on an amazing restaurant or getting the best seats I can find at a show than on a room that sits empty most of the day. When the host and guest click with each other, that's a real bonus - a local contact who can offer a special tip and a more memorable experience. If you don't really click, no big deal - traveling keeps you busy, you won't see much of each other anyway.
But for people traveling during the pandemic, none of this really applies.
The Homestay model of hospitality is not intrinsically built around the host offering a round-the-clock office space or full-time self-quarantine (though plenty hosts are totally happy for guests to just be alone in their room keeping to themselves all day). The presence of a stranger in the same dwelling all day long can be a major anxiety trigger for both the host and the guest. Ali, it sounds like you were diligent about communicating your needs, and of course this host was way out of line in every aspect of her behaviour. But I'm struggling to understand how you reached the conclusion that a room in a shared home (and, particularly, this one) was the right fit for you in the first place, when what you needed most was peace and quiet and privacy. It sounds like a hotel or self-contained apartment would have been more appropriate all along.
Perhaps one takeaway here is that in these times, when self-isolation is forcing home-sharers to spend the whole day together, it's far more important for hosts and guests to communicate well before booking and establish that they're likely to be a good fit for each other's personalities.
