Hi Flamedlight,
Growing up in my teens I had a lot of friends in the Netherlands and I visited regularly around the Arnheim and Utrecht areas. The most common greeting I heard was 'I'm sorry, my English is not too good'.
Let me tell you your English is better than many English people - as shown by your correct use of 'to whom'… and I can guarantee it is better than (m)any members mastery of Dutch

That being said, I hope you find the answers you are looking for here, and that your stay is long and fruitful.
Dave.
