Olena was the best of the best I’ve ever been to with Treatwell. Fantastic vibe, so knowledgeable, felt like I was in very safe hands. I left feeling and looking younger and even better the next day. She’s far above average of anyone I’ve seen for facials. Felt like I was in a specialist office at home in California. I’ll be back to her whenever I am in London for work. 5 stars!!
