Lily's Nails in Holborn is my go-to in the city. The environment is so chill and quiet, and the nail technicians are the best in town. Though pricer (still adjusted to city prices) I think the quality and experience are worth it
She was the nicest person ever and so fun to chat to!! :) Also my nails look incredible, she had so much attention to detail, definitely my go-to spot now (also such a good price)
