First off, if you have issues or sensitivities with dust / mold then look elsewhere. The house is old and it isn't clean.
But if you're just looking for a place to lay your head for a few nights at an unbelievable rate (there's a double room if you're traveling together and you'll pay less than $10 each) then look no further.
Personally, the mold is not something I would live in long term, but for short stays you just can't beat the pricing. Jinu was a great host and everyone I met living there was nice / helpful to us (as we were new to the country and the area). A huge plus if you're an animal person is the friendly cat, Nero, who wanders in to hang out from time to time.
Again, not the type of place I felt like spending a lot of time in, but just so cheap it's hard to pass up and I would stay here again.
