What is the sentiment of the following review?
My wife took me to Cloud 9 for our anniversary. I had never had a facial or pedicure, so I was interested to try both, as well as get a massage. I started with the massage and it was so relaxing that I fell asleep on the massage table. The facial was definitely more relaxing than I had anticipated and I can see why it is that women get them so often; my skin felt so refreshed afterwards! I was the most excited about the pedicure because I have a lot of cracks in my feet that are impossible to get rid of, no matter how many products I try. They were able to get my feet almost completely smooth and I booked another pedicure for two weeks from now.
