The only frequently asked question that we can add:
What is the weather like?
Usually it is 5-10 degrees above zero; it might be windy or raining… Good weather to study… What about the pictures with snow and ice skating on the website? Well… That’s if we’re lucky. The Dutch like ice skating because this opportunity is quite rare. But don’t worry… there are enough artificial ice skating rinks.
