It's better if you are on a similar level to get out as much as possible of your lesson. If you not are on a similar level and still want to have class together we recommend you to book a family lesson instead. Even if you not are family.
Prices shown are not per person, but for the whole group. The price of a group lesson is the same whether you are 3, 4, 5 or 6. It only depends on the number of hours you book.
