I experienced friendly service and a great wax at Charmi's, only downside was a walk in was accepted at the same time as mm appointment, so I had to wait 15 minutes.
Even if the staff was really kind, the place seemed a bit messy and untidy. If you for waxing, that is the last thing you want as hygiene reasons are involved and also it is unsettling overall. Nevertheless, the lady who did the waxing was nice.
A little bit difficult to find as it is at the back of a barbers on Camden high street. However a great eyelash tint and a great price, I will definitely return.
