I've been in Spain, Belgium, Germany and Italy. I'm planning to go to Holland and Denmark and Greece.
I can reccomend you Spain because there you can really be a traveller, a friend of mine went in Spain and stayed for almost 1 year, just travelling for the whole country.
I can reccomend you to go in Belgium because of the beer's ahaha.
Also Switzerland where I live, is wonderful and also wonderful panoramas. I think you'll enjoy here, chilly place with beautiful mountains and food.
I also went in the Black Forest in Germany, if you have a chance, go to because it's AMAZING
