I visited Amsterdam once and i loved exactly what you just described! Maybe it's just me but i get the sense that in the Netherlands the air seems to be much more clearer. I swear i felt like my lungs were going through rehab...but then again i was a smoker for 5 years and i quit 2 years ago. The air there gave me new lungs! and i will forever be grateful. The more that i talk about it. The more that i feel like i should go back, i.e visit one more time.
