This is basically a mother-in-law apartment. It's the basement of what I assume is the owner's home, which means you will hear all of the things you would typically hear in your own home - talking, TV/radio, microwave or coffee maker beeps, dishes being set, etc. If their sleeping and waking hours don't match yours, you'll know that too. Hence the four stars.
Besides that one issue, the apartment was exceptionally clean. We've stayed at a lot of VRBOs, but this one was probably the cleanest. There is a ton of space - more than the pictures accurately communicate. The five of us never felt crowded. Most of the appliances were brand new. The beds were very comfortable. The kitchen was stocked with the cooking basics (just a two burner cook top and no oven), but St. George has a plethora of excellent eating establishments. The rental is located in the Ledges community, which is a small, quiet neighborhood with very friendly people about 10 minutes outside of St. George with lots of walking paths and pretty scenery. We were there for spring break and St. George was CROWDED! It was nice to come back at night to where there were less people and no crowds. The community is just a couple of minutes away from the back entrance to Snow Canyon (a must see!). There was plenty of space for parking. They mean it when they say you could get an RV, camper or other toys in there. I even saw electrical outlets along the driveway. All in all, a nice place to stay.
