I was in Copenhagen over the weekend and had such an amazing time. I got in last Friday and left on Tuesday morning. I walked around everywhere and managed to tour Rosenborg Castle. I did a few museums too.
I even made it out to Aarhus to see my friend who's doing a PhD program there - and took a picture of the Aarhus skyline too, thanks to my friend who guided me up to the roofdeck of a local mall.
I plan on coming back.
