I booked at short notice (an hour in advance) and when I arrived they said the they didn't have a vacancy (despite it appearing on treatwell) and that they rarely acknowledge treatwell booking. If you were to book with them I would recommend calling also to confirm.
The salon is a lovely place a short walk from my office, with a very relaxing soothing atmosphere. When I arrived it seemed there had been a problem with my booking and they did not have my appointment on their schedule but still managed to squeeze me in in no time. I had a full leg wax, which was done very quickly and neatly. Lovely staff, very kind and very good. Strongly recommend!
