Although I didn't meet Julianna, Carlos was very friendly and helpful-- as this was my first visit to Vegas. Although my map app gave me wrong directions, their place was actually easy to find.
My room was clean, and cool in the 104 degree heat. The only thing I could suggest is that they make a note for future Airbnb travelers to leave the shower water on for a few minutes so that it can warm up.
Clean towels, soap, and some other toiletries are provided, and Carlos checked up on me to ask if I needed anything else.
If you're looking for great value, and closeness to the airport and the Strip, I recommend staying at Julianna and Carlos's Airbnb.
