The first treatment I had was a spray tan which ended up being v patchy. Before having it done I was given no advice regarding what to do before the treatment.
If you have an appointment in the evening you have to wait outside for someone to come and let you in so I recommend not arriving early because you'll just be waiting. Because of this the second time I booked an appointment I ended up waiting for 15 minutes (in the rain) before giving up. When I contacted them the next day I was told they hadn't booked in my appointment and was made to feel like I had made it up.
Would never go there again.
