Rachel's place clearly had a lot of time and love put into it, and it's extremely safe and well-protected, as well as private! If you're a solo female traveler, I'd highly recommend this listing. It's very aesthetically pleasing as well and has everything to make a long stay comfortable.
However, the stairs (although they are warned about before booking, which I appreciate!) are honestly unsafe for any person, no matter age, agility, or strength. They're graded a bit too steeply and have no tread. I think this would be easily fixed by adding some carpet (or tread) down them and replacing the railing with something that's grippable.
