Zaragoza, for example, is a great destination for a two to three-day trip or as part of a larger train trip through Spain, Sturzaker said.
"It has a bell tower that you can go up for really nice views of the city as a whole."
In Zaragoza, Sturzaker also explored Roman ruins, from a theater to public baths.
Sturzaker recommended walking along the river or taking a tram to the Guggenheim Museum if you're a fan of modern art.
"Don't miss the viewpoint and Funicular de Artxanda for wonderful views of the city from above," she added.
