City Break Suggestions Please

[curlyfries81]

Four ladies who want a city break not too far from the airport. We are happy to travel to the less well-known cities - a friend suggested Varna in Bulgaria and we will certainly consider that one, but we will obviously consider the major cities as well. We've done Rome, Barcelona, Paris, Krakow, Athens, Venice, Reykjavik and Lisbon between us and don't really want to go to anywhere we've already been to. 

Thanks in advance.

I'd recommend Budapest too.  Lovely.
 

How about New York?

Hannover has piqued my interest before now - it does look lovely.  Seville is definitely on the list.

We're looking for shorter-haul, Naomi24.
