Not tried this myself, but a couple of answers from a quick google search:

I walked into the ING bank on Haarlemmerdijk last year and broke 6 €100 bills with no issue or charge.

For what it's worth I changed a 500 note at GWK at Schiphol Plaza back in 2013, had to pay 1% commission
LOL at least you don't have €500 notes...
Personally (based in the UK) I like using a Halifax Clarity Credit Card to withdraw money, you get the official Mastercard rate with no % added, no commission and no withdrawal fee. All you pay is the actual interest on the money you withdraw, until you pay it back (which you can do with an online transfer as soon as you get home... on on your smartphone while you are away, I suppose).
For example I took out €190 on Wednesday last week and it cost me £168.93 which is a rate of about 1.125 which is pretty much what you will see if you look at the currency markets for that day.
In terms of interest, if you take out €1000 and pay it back after one week, the interest (typically 13% APR) works out at about €2.50, which is a lot less than any currency provider will be making off you when you compare the rates they offer to the official bank rates.
The ABN Amro cash machines tend to be the best as they offer a choice of note combinations so you don't have everything in €50s. The Travelex machines ask me if I want them to set the rate or "continue without conversion" ..... it's a difficult choice whether I want Travelex to cream about 15% off the top, they were offering something daft like 0.97 euros to the pound when the bank rate was about 1.12
