Salon de Nouveau is located near Fort Lowell and Campbell in a very nicely decorated little building. It is a comfortable, pleasant atmosphere. Everything is clean and tidy. The staff are reasonably attentive to your needs, often offering water to drink. I found this to be a pretty typical salon/day spa experience. They offer a wide variety of services, such as manicures, pedicures, massages, and hair styling. Nothing stands out as particularly great, but I've had several good services there. Prices are a bit high to me, but again pretty typical.
On the plus side, I was given a gift certificate for Salon de Nouveau, and I used only part of it. When I finally got around to using the rest of it (1 year later), the certificate had already expired. I called them to make an appointment, and they gladly accepted it.
