I am planning a trip with my mom in late May early June. We are going to Copenhagen and Stockholm, but I am looking for a 3rd city. We will be spending 9 days there, I am thinking 3 days per city more or less. Any suggestions...? I have been looking into Amsterdam or Oslo. Which is better? Any other suggestions?
My mom and I have traveled quite a lot through Europe, I'm just trying to find a city that goes well with this itinerary and that we haven't been to yet.
