Which city should I choose?

I can get a free return flight ticket to a European city . I'd have to pay my stay and airport taxes and stuff though. And I have to choose from the following cities:

Barcalona
Berlin
Brussels
Geneva
Lisbon
London
Luxembourg
Nice
Riga
Zurich

I've been to all of them except Zurich and Geneva. I visited Barcalona and Riga very briefly, in the other cities I've spent several days if not weeks. But which one would you choose? I obviously can't decide and I don't want to spend too much money .

For when is it planned ?

I'd go for Lisbon, but you say you were there already ...

Zurich and Geneva would be the best as you've never been there but if you don't want to spend too much money once you're there .. well ... not sure it's the best option

I'd go for Lisbon !

somewhere in between now and June!

I really don't mind going to a city for a second or third or fourth time... Especially Lisbon, I was there with my parents when I was about 9. I can't say I remember much of the city .

Lisbon and Barcalona are actually on top of our lists! But we're just not quite sure yet .

Yes barcelona would be my 2nd option too

Lisbon !!! And i think it's one of the cheapest town in all those ??

I think Riga is probably the cheapest, but apart from that I think Lisbon is relatively cheap compared to the others .

So depressing I've never been to any of them....but I'd go for Barcelona!!! It's where I want to go living next year

One thing is sure : you musn't choose Nice if you don't want to spend too much money

I think I would choose Zurich first,
Then Riga and then Luxembourg

I heard very good/nice comments about Lisbon. I'd choose Lisbon or London or Barcelona, if I were going for the first time. Otherwise I'll choose a new city to visit, Nice would be a nice option but I don't think it will be a cheap one.

Good luck with your choice and lets us know which one you picked.

I've never been to any of those cities, but I'd probably pick either Barcelona, or Lisbon.
