Ughhhhh I have a love hate relation with these type of list-icles. Love their easy to read, but hate the American-centric criticisms of this article.
TBH, each country deserves 2-6 months of properly slowly discovering and enjoying the time there. Short period stays aren't enough!
I really enjoyed the Vatican, but I also picked to visit in the late afternoon/early evening. No crowds, wide vistas of the entire plaza, and no lines to visit inside!
Monaco was.... severely disappointing. I did a day trip there from Nice during a 3 week solo European tour. Was bored out of my mind after visiting the casino.
Lived in the UK for 2 years in South London. Thankfully food wasn't boring because I hung out in the more immigrant heavy neighbourhoods. Weather is pretty miserable in the winter, that's true, but I did find people friendly, despite the stereotype and the fact of making local friends was a difficult task.
Spent a few days in Malta (read: Valletta), it's absolutely gorgeous and lovely. Being a vegetarian, holidaying on an island nation is not without it's difficulties, but that's on me.
Switzerland was too expensive for my liking. Gorgeous and beautiful, but... oh so effing expensive.
Czechia (really only Prague) was great enough for me, despite the large crowds. Must return to explore more (and maybe meet one of the Bel Ami boys?)
France was fantastic. All the museums, art galleries, and the la belle vie elements I could ask for.
Vienna was probably one of the most breathtaking cities. All that old empire grandeur continues to impress.
Germany was great, and at the time, vegetarianism was picking up so lots of choices were available (albeit more expensive). The guys were hella cute, hella adventurous and keen to have some public fun >
Italy was worth every penny I saved for a separate 3 week trip. Still not enough time!
Amsterdam is fun, but other cities deserve love too!
Barcelona was too overcrowded but I prefer it over Madrid. Missed out on visiting the Southern coast, must return in the future
Denmark was fantastic. Would for sure visit again. Have a super hot story of my time in Copenhagen.
