This was a nice little stay while visiting my family- surprisingly well lit despite being a half basement. Couple things worth noting, though they didn't really detract from my stay-
1. I believe the listing says this place has low ceilings, and it's not kidding- I'm 5'11" and when I stood up straight I'd hit my head on the ventilation ducts, so I kinda just got used to leaning a bit. Still bumped my head once or twice, but not hard enough to hurt. If you're 6'2" or so, you will probably hit the ceiling- I could if I was on my tiptoes.
2. The aforementioned ventilation duct carries sound with shocking clarity, so if you're noisy or trying to work evenings here, it might not be the best fit. I wasn't in the unit much when not sleeping, so it was not a problem for me!
3. The floors are concrete (though finished and pleasant!) and can be a bit cold without socks/slippers, so I'd recommend accounting for that while packing!
All in all, a really accommodating, easy stay, and I'd happily stay here again.
