Can't comment on whether studying in the Netherlands is a good idea re: future employment, however my DS is currently studying in Amsterdam (we're from the UK) so I can give our perspective.
He's coming to the end of his first year. He doesn't speak any other languages apart from English. He took Dutch lessons through the uni (small cost) and enjoyed them, but finds everyone he meets socially wants to practice their English on him so he isn't getting much chance to practice Dutch!
Finding accommodation was very hard (though your DD might be provided with some through her uni??). He stayed in a hostel for a few weeks, then a house share with two working adults. It was an hour from the uni and he found it hard. Also, he found it difficult to make friends coz he wasn't living with students.
He moved at Xmas to a place much nearer his uni, and has made a small group of friends. He loves the course and the city, and doesn't regret it. But I do think the stress of being abroad and trying to sort accommodation and having no friends was hard for him. He's someone that's happy with his own company, and finds himself stuff to do, but if he'd been a real people person I'm not sure he'd have coped.
It may be entirely different for your DD of course. We send him £550 a month which covers accommodation and living expenses. It's a lot of money and although he will benefit re: much less loan, it would've been cheaper for us if he'd stayed in the uk. He recently got a job, just washing up, but that'll help.
Finally, you have to pay the £1500 tuition fees upfront, end Aug I think it was, then have to apply for the loan before end Jan. You can't apply until you have a registered address in Amsterdam, which he didn't get for ages. With his first accommodation he wasn't registered because he was staying in an extra room. Apparently that's not uncommon.
A lot to think about! He does like it though. He got an old bike for twenty euros and cycles everywhere. On a set day of the week everyone puts any unwanted stuff outside their house for anyone who wants it to collect, and he got his furniture free that way. The uni is very multicultural and he has made friends from all over the world.
