DH and I are looking to plan a trip to Europe. I was thinking Spain. Something quick(5days) to see Madrid and Barcelona. No kids.

We enjoy the hustle and bustle so don’t be alarmed with the quick days. We did London quick and enjoyed it.

Just trying to see the touristy stuff for both major cities.

2 days in Madrid and 3 in Barcelona? or vice versa?

What to avoid? Must see? Restaurants?
