LIKIMIO Canopy Bed Frame Queen with Storage Headboard & Charging Station, Sturdy Metal Platform Bed with 4 Removable Posts, Dual Purpose Bed Frame, No Box Spring Needed, Noise Free

I lived in similar accommodations during my time working in National Parks. What I liked and found the cosiest was a canopy bed frame. There are affordable options on Amazon. I’d take something like this one, change the curtains for something more opaque, and add panels at the front. It’ll be your little nest.
