We stayed here for just short of a couple months, and this is one of the easiest 5-star reviews I've ever written. It's actually quite hard to imagine anyone complaining about anything at Christina's.
The house is spacious, well furnished, with a fully (and I mean fully) stocked kitchen. The neighborhood is traffic-free and quiet, far enough from the strip to get away, but close enough to see a sliver from the back patio (easy 10-minute drive).
Yes, the King Bed is the master is amazing, but we found all the beds to be comfortable. WiFi was super fast. Christina was very accommodating and friendly. It's conveniently located with short drives to several parks, grocery stores & restaurants.
If you're coming to Vegas, I couldn't possibly recommend staying here more. We'll definitely be back. :)
