I recently had my nails done here for the first time and was pleasantly surprised. The staff were lovely. The service was fast and fairly reasonably priced for nails. It is also conveniently located between the city centre and the train station. I walked in without an appointment less than an hour before closing and the service was still excellent. I would recommend this nail shop if you're in Cardiff!!

I had my first ever pedicure experience! I usually get my nails done but was absolutely amazed by how lovely and relaxing it was . Also you get a back massage from the special chair and a foot spa.

I came in for the first time to get my acrylic toes done after seeing my friend's gorgeous French set, she recommended this place and I couldn't be happier with how they turned out! My toenails were fragile and misshapen when I came in and now I've come out, she's added a whole new confidence in having my feet out. Definitely look forward to coming back again and suggesting this salon to my other friends as my nail professional, Mina, was super gentle and so lovely and sweet.
