Karolina is friendly and kind and the salon is clean. I had a g-string wax at it was well done - quite painless.
The only cons are that the salon is difficult to find: I expected to see Karolina's Beauty Salon written outside the building, but actually the salon is at the lower ground floor of a hairdresser salon called Tangled (or something similar). Also, it is not a proper salon as I expected it, but simply a room with everything inside (both the beauty area and the reception desk). However it was clean and wax was perfect, so I do recommend it!
Today I've had a shellac manicure and pedicure by Karolina, a very lovely lady who knows what she is doing and she did a great job with my nails. My little toe did not agree with that, it didn't take the shellac, propably because it is that small and weird but it will not stop me going back! :)
