What's your favourite city you've visted?
Oo that's a great question! Hope you'll forgive me my very euro-centric answers, since those are the destinations that are compatible with my current travel budget
I mean if I had to choose one it would be Paris, which is probably hardly a surprise for anyone. But I think it would be the case even if I wasn't into the French Revolution/French history in general. There's just so much to see! (Also, I got my coffee replaced for free after I spilled it all over myself like an idiot. So Paris gets additional points for that)
I also like smaller cities, especially the ones which you can explore on foot. I've recently been to Verona and really fell in love with the place. Also Tallinn (the capital of Estonia) - I think it's criminally underrated!
Oh, and I know that one doesn't count, but Prague isn't half-bad either of course.
