I've been getting facials in Las Vegas for over 10 years. I have a few favorite spots but decided to try ESPA at Vdara because I was staying there. The arrival experience is very good and customer service is on point. The locker room area and physical environment is also quite nice although I did not use those areas for any more than getting ready for my facial.
The reason I give this spot 3 stars comes from the esthetician adding a service without communicating that it was an extra or that there was an additional charge. When I checked out, there was a charge of $60 on top of the $250 base charge. An add of almost 25% is not something to be subtle about.
