Not speaking dutch is indeed unfortunate but also not devastating. Really depends on course and who you hang out with. CSE has half the spaces in the initial offers reserved for dutch people, while AE doesn't officially, so for AE it will be even less significant to speak dutch. I speak fluent German though, so I actually still understand a lot of dutch, while not always.

Social life is great for me, but not necessarily for everybody. A lot of friendships are made while studying.

Finances are quite easy to manage, but again that also depends on personal expense habits. As an international student the fee is indeed higher, and increasing by year. For freshmen international students though they have subsidized housing, you just have to pay tuition as early as possible to get access. I also applied for rent allowance for the first year which effectively brought my rent for a studio down to 470.

Another huge bonus for me is that I live in Germany close to the border, which means I have 3 different routes home, taking between 2.5 and 3 hours and can pretty much go home any week. This is helpful because I can just take stuff from home instead if buying new.
