I highly recommend Kensal Nails. Its easily accessible and the staff are very friendly and refer to you by name. They always offer you a drink be it water or tea and coffee. They're interested in you as a person and take time to listen to you. I feel comfortable enough to have shared personal experiences and events with the manager. He recently surprised me with a bunch of flowers when I attended on my birthday. It was such a lovely touch and really brightened my day
