I really liked both of my service providers (Ashley and Jessica?). There aren't many spas that offer the Vichy shower in Minnesota, so I appreciate that Solimar does (and the providers always do an excellent job at draping with towels, etc.)
I also really like the Oasis room, and purposely planned on extra time between my services so I could just relax there. The chairs, blankets, ottoman and dim lighting are lovely.
I know it would be a tough upgrade, but it would be wonderful if there was a steam room or sauna (or hot tub)!
