We’ve just returned from Porto where we went for 48 hours. It was brilliant, just the right size for a short break, very walkable, great food, lovely atmosphere in the evening by the river. We felt like 48 hours was the perfect amount of time there (I know we could have spent longer and explored outside the city more but loved the convenience of the small city).
Any recommendations for other small, walkable, cities where 48 hours is a sensible amount of time to spend there?
