The best spa experience I've ever had. The ambiance is spectacular - it's all espresso wood and slate walls with water features and glass staircases aplenty. The staff was very polite from check in to check out.
I had a 25 minute herbal bath, a hot stone massage and a manicure. My mani lasted for five days without chipping, and the hot stone massage...well...I wouldn't have minded if THAT had lasted for five days, too! So relaxing! The bath was nice - you're basically sitting in a tub full of tea, in a darkened room with a ceiling so high you can barely see the top. I do wish the music in there would've been a little louder, as I couldn't hear it over the roar of the jets. Overall, Bathhouse was an amazing experience, and I'm definitely adding it to my "must do when in Vegas" list!
