Perfect morning at the spa! It was a birthday treat from my daughter....I enjoyed the Experience Room and the Salt Room. Both were very relaxing! Spotless facility and top notch staff.

Great experience!! The staff was welcoming and the space is beautiful. Sasha, works in the spa and she performs my brow tweezing. She does a perfect job! She is the only one I trust to shape my brows! I’m always so pleased.

From day one of going into this spa I was greeted by Dave treated very special all of my needs were taken care of. The staff is professional, respectful and ensure that you have a wonderful time. I love feeling more relaxed than when I came in I so appreciate the staff taking that extra time to make sure that my needs were mad and that I was okay this is what service should look like 365 days out the year.

I received an incredible signature facial from Alina! She was so kind and knowledgeable, and she took the time to discuss my skin concerns with me. I felt so relaxed and rejuvenated after! Also, the facilities/amenities at this spa were fantastic. Overall very impressed and I’ll definitely be back!
