I've had several waxes at Sophia Esthetic. The staff here is very friendly and goes out of their way to make sure you are comfortable during and after the treatments they provide. Excellent customer service and it's clear from my experience that this customer-focused mindset comes from the owner all the way to the various employees.
The place itself is extremely clean, calm, and comforting. I especially appreciate the touch of calming music and a nice salt-lamp to create a nice atmosphere for the treatment.
One heads up: the exact location can be hard to find if you don't know where to go through the building, so make sure you ask how to get into the building if it's your first time. But it is excellently located in central Ottawa, has competitive prices, and like I said great customer service.
