Very small, but really lovely Airbnb. Do note that this is not a "guest house" — a guest house is a standalone unit — this is part of the house, with its own entrance and no connecting door to the main house, and in Vegas they're usually referred to as casitas. But that didn't matter, it was EXTREMELY quiet, private, in a quiet part of town, and, unlike one other reviewer, I did not hear a peep from the hosts whatsoever.
The unit is SO adorable, so well decorated and so clean! Fully modern kitchen and fully modern bathroom (albeit shower water pressure, just 'ok'). Both look new. Parquet floors, or at least they look like it. Huge flatscreen TV on the wall which, for some reason, I barely used. And a very comfortable bed. It is adjustable by remote control but I chose not to use that. They have blackout screens and curtains on the one window, so the room can be VERY dark in the morning if you want, which I did — and I'm very sensitive to light, so I was very grateful.
The owners, a middle-aged couple, are SO nice, gracious, communicative, go out of their way to make sure you are comfortable. Their primary language is Spanish; but if there is something you need that they don't understand, they call their daughter to translate, really great.
This is a unit that is absolutely perfect for one person, like I was during this trip, and works very well for two people — as long as you're not fighting and need your own spaces! lol It is very well situated between The Strip and Airport on one side, and Green Valley on the other.
I wouldn't hesitate to book this again. It's a great value.
