We are looking to go away on a city break first week of the easter hols. DH, myself, DDs (9 and 4). Not looking for somewhere warm necessarily but with decent number of sunny days (mid teens is good). Nice architecture, good food, lots of culture/museums, pedestrianised streets and plaza - that type of thing. We've previously done Seville & Granada one year, and Tuscany last year around easter which we all loved.
Where can we go? I've looked up Provence and am quite taken with the idea of going to Aix. Any other suggestions?
