You're right about the hosts, a lot of them are not interested.

But I still find people on LeBonCoin who are. They like to fill their appartment/home and not bother for a month, it's convenient. I might clarify that I find them not in big cities though. That might be the point: hosts in smaller cities are interested. And like you said, there are also people who rent on holidays and not the rest of the year. Plus, it's cheaper since they usually don't have anyone.

Like you said, "monthly rental are not really a thing". It's hard to find without being there. I usually look on the internet (mostly France for now, I use leboncoin.fr) but it's time consuming. I always need to explain to people why I do (they don't really understand why I'm looking for a month), I need to negociate the price, be sure there is a good internet, etc.

I'm thinking of an Airbnb just for this: rental for nomads with monthly rates (and other things that matters like a good connection). I'd love it for myself at least, but I guess it could probably be useful to other nomads.

I prefer physical books since I spend most of my day on a screen. I like to "feel the paper" in my hands too, rather than holding a screen. But I actually never tried a Kindle, I might like it.

You need to create an app extension, in your case a share extension. I don't get the "fastest" part of your question since I don't see another way to do this. I might have misunderstood your question though.

Thanks! I'll look into it.
