The property was off the main strip but it was still in a decent area. The staff was awesome! Wish there was more places to eat in the area and there was early check in available.

We rated the property a 3 because the beds were comfortable and parking was included. Communication was prompt and thorough. We booked the Penthouse, sleeps 6, we did not understand that this was a walk up. Midway in the stay the stairwell smelled of death with huge flys. Really gross. There are only 3 chairs in the living area, very uncomfortable to hang out in. The kitchenette was quite poorly appointed. 2 juice cups, 1 wine glass, no oven, microwave or toaster. No cleaning services were offered during our week long stay. We did get to exchange towels toward the end of the week. There is a loud club located directly across the street. Bass thumping and people yelling all night long. Not recommended for families! *Excellent restaurants in the area.
