I made an online reservation during a bank holiday for the day after, and the day after in the morning I received the appointment confirmation, so the booking system is pretty up to date.
The entire appointment took exactly an hour (as advertized) and I was very satisfied with the result.
Although my Dutch is quite poor, the hairstylist understood exactly what I wanted (wish & fears), and did exactly what i wanted.
Both stylists available this day were very friendly and service oriented.
Bonus: super nice head massage with the shampoo.
If anything: the salon is very big for so few hairstylists, and the black & white decoration makes everything pretty cold. but again, it did not bother me.
