I think this is what people did some centuries ago: Wake up in the middle of the night and do some stuff, then go back to sleep for a couple of hours. See [1].
I also have issues sleeping. When I sleep at my parents house, I sleep excellently. I did sleep there for a week a couple of months ago and I never felt so good. The downside is that my girlfriend gets upset when I sleep there for a week (and my parents think I'm in a fight with my girlfriend).
Things that might explain why I sleep so much better at my parents house are:
- It's darker
- It's less noisy
- There's a better bed
- There's no-one sleeping next to me in the same bed
- Maybe I feel safer if I sleep on the second floor of a big house instead of right next to a street?
Ah, yea. Varying sleeping locations, I've done that a lot, unintentionally. I've slept in humble homes to mansions to far out locations (my own place being a humble home). My best sleeping moments are when I go camping and rise and fall with the sun. That's the only time when I am capable of sleeping normal, waking up and falling asleep with the sun, no clock needed.
Here are my experiences to what you said.
It's darker: I use a sleeping mask.
It's less noisy: I used earplugs but I have tinnitus and it acts up when I do that. Currently though, it's not noisy because of Covid. Maybe I should have a noise cancelling / ambient white noise system. The normal tinnitus levels don't bother me, airplanes flying do.
Better bed: turns out, I love a mattress on the ground the most.
Sleeping next to people: that's funny, I sleep better sleeping next to someone! Well, we all differ.
Regarding safety: that's how I feel when I sleep next to someone. Not that I feel unsafe sleeping alone, not at all. I simply feel safer.
