Everything very much depends on the master. The first time everything was great, the last time they painted it very badly, the master did not do what she asked. I was afraid to say directly, because every girl there works for herself, it is unknown what they will say, how they will behave to criticism.
I boldly put four stars, because only once did something go wrong.
Do not hesitate to explain the desired result to your master in detail, so there should definitely be no problems.
