I had a body scrub and facial here with the same aesthetician. I believe her name is Ashley. She did a great job. The facilities are what you expect from a luxury spa on the strip. They provide robe, slippers, drinks and toiletries.
I had the facial and then body scrub. The aesthetician then suggested I sit in the steam room before rinsing the scrub off and it was great. Very relaxing, large steam room. I then showered off and used the body lotion she provided for me.
The facilities are fantastic. There's a hot, warm and cold plunge pool. Plenty of lounge chairs for resting. They even provide chilled cucumbers for you to place over your eyes. The plunge pools are bathing suit optional, so you don't have to worry if you didn't bring a swim suit to the spa. The atmosphere is very comfortable and I didn't feel weird without a suit.
It's an on-strip vegas spa, so the pricing is at the higher end, and so are the services and amenities. This isn't a place for quick cheap services, give yourself a few hours to really enjoy everything they have to offer.
