I can suggest you some more:
Copenhagen and especially the summer bar street called Nyhavn is great, our Danish girls are very nice
Go to Switzerland, Austria and the Bavarian part of Germany, then you will be visiting the Alps, rent a convertible and drive those sensational beautiful roads in the mountains or just take a trek.
Rome is my favorite city in Europe, but it can be very hot in the summertime - but there are so many things to see.
The Spanish city of Barcelona is also very great.
If you are up to just relaxing and enjoying yourself at the beach some of the Greek Islands are great.
