Trying to see one more place in Portugal, besides Porto, which we fly out of. We'll be in Spain for 9 days, which leaves 6 for Portugal. We will be there in December, so a preference might be places suitable for colder/potentially rainier weather (we are from Portland, so very used to walking around in the rain and still having fun).
In doing some research, the Coimbra and Guimarães came up as potential places to spend 2-3 nights.
Anyone been and have a preference between the two?
