I was born and raised in London. Some people hate it for having too many people. But I love it and I love showing tourists around London. It has everything you could ever dream for. Especially if you dream of huge crowds!
Paris seems to be a place that people either really love or really hate. I love it!
Barcelona is definitely my favourite city in Spain to visit. It has a great nightlife, fantastic weather in the summer and is a really nice city to explore
Lisbon doesn't seem to be that popular compared to many of the other capital cities in western Europe, however it is completely charming and I can recommend it to almost any type of traveller.
Hungary doesn't have too many different tourist spots - almost everyone who visits just goes to Budapest. But it is a very, very fun city. If you're going abroad for the nightlife then you won't beat Budapest's crazy ruin bars.
Munich is one of the most expensive places on this list, however it is worth the Euros. Especially in September or October for Oktoberfest.
