One of the best mani & pedi I had in London. A shame the ambiance in the salon is not great (uncomfortable chairs, no music, a bit cold). If you don't care about that, strongly recommend the place, the service is amazing.
Nail Lounge is easy to find, just head for the back of the shop and down the stairs. Greeted well and had a fab manicure for £13. You can't go wrong with that. I will be back for sure.
