This was one of the NICEST nail places I have ever been to. I had my first BIAB experience decided to do my bridal nails here - they were so so thorough, gentle, and kind. Explained the whole process from top to bottom to me and aftercare advice as well. I had the luxury of getting a pedicure as well on a massage chair, and was offered hot drinks with their professional coffee machine. I truly felt cared for and will certainly be going back!

Been coming here for years and the new owners who took it on are a lovely friendly couple, warm and welcoming. Offered a drink, have a chat and a giggle while getting my nails done. Always great quality service and always love getting my nails done. Loads of colours to choose from, gel, biab, power, nail art, chrome whatever you wish also do toes and other services. I wont be changing nail bar this one is the best in town and good pricing.

This was my first visit to a nail bar as I was fed up with my own nails splitting & breaking, probably due to my medication. I was over the moon with the welcome I received from Lucy yesterday afternoon. I'm thrilled to bits with the results of my nails, they look very pretty. I was introduced to her husband when he arrived shortly after, who was equally as welcoming. I was offered a hot drink too, which added to the welcome. I will be calling again for infills in about 4 weeks & have joined their loyalty scheme. A truly pleasant experience - thankyou Lucy. See you again soon

Diamond nails are so good. These are the best nails I've had. They do not lift. So much care and attention goes into the work done. I wouldn't go anywhere else. The service is 100%

I needed an infill and my normal place was full. As soon as i walked in i was offered a hot drink and to have a look through the colours. They asked me what service i was after/design/prices. Had to wait ca 15 mins which was fine. Both owners happily chatted to me which was nice. Removal/filing etc was gentle and no pulling of hands or fingers. Everything was brilliant and i am pretty pleased with my results..might even try biab next time as i might of found a new salon to go to. Keep up the good work, 💅

5* Nail Salon. I visited for the first time after moving to the area and I can honestly say it is the most welcoming salon I have been in. It is run by a lovely couple who are great at what they do. A nice latte from the coffee machine was also a great touch. A lovely service with a lovey French manicure. Will definitely return. Thankyou x
