For me these are the things that annoy me over here:

It's VERY busy. Almost impossible to get away from it all and take a rest, constant traffic jams and public transport delays

Taxes are dreadful, I have my own firm and more than half of what I make gets given back to the state without me getting any decent back from them

The Dutch are not very service minded, this is something that has declined over the years, finding decent hardworking service oriented staff is tough

As the previous poster said: bureaucracy, it's dreadful, even the easiest task runs into problems at the moment, this too is something that has become worse over the years...

Don't get me wrong, Holland has been very good to me, but the current political climate here is spoiling the place.
