I'm really suprised by some of these replies
Bratislava, Slovakia. Most boring city ever extremely expensive and really not much to see or do Are you joking? It's as cheap as chips! I love Bratislava. I went three times this year, twice by myself and once with DH. Loads to do. A national park is a short bus ride away and loads to do ( including a cocktail at the bar which rotates in the television tower. There's also the cable cars and mechanical bobsleigh.
Barcelona is my happy place and I have booked a flight for March with my cousin. She is nervous about pickpockets. I have never seen or had any trouble is the 20plus times I've been in over 20 years. However I guess i must look poor! I don't wear a watch or any jewellery and I carry an old battered rucksack with nothing of value in. I just try to blend in ( as I do in most countries) and stay alert. I guess my luck may run out one day but so far i've loved it.
I have been to Berlin 11 times in the last 6 years. sometimes with friends, sometimes by myself but love it to bits! A week, never mind weekend is never long enough.
Brussels? me and my friend often do it as a day trip if we get a flight cheap enough. It's alwaysgood fun.
It's some years ago now, TBF, but: Oslo. Appallingly expensive. Lots of 70s-style shopping precincts and apartment blocks. Locals with unironic mullets and stonewashed denim. Everything was shut on a Sunday, like small-town England in the early 80s
While I agree that Oslo is expensive I love that place! Well. love it in the summer time, it's not so great in winter for me. However in summer I love being at the Astrup Fearnley Museum of Modern Art and around that area on a lovely day, or reading a book in the Palace gardens. Fabulous place and great for a weekend.
My dull place is Szwcerin. However it is easy enough to get the bus over the border to Germany and go to Berlin instead.
I'm surprised at Edinburgh as well. Its only a couple of hours from where I live on the train so I go up there a lot. So many districts to visit, It's got everything from a beach nearby, cool bars, great charity shops, fantastic buildings, independent shops, lots of historic buildings and so on. There is always something happening that's cool.
My worse holiday destination was Jamaica. Montego Bay was intimidating, However it is my sister's favourite place.
