Several times. Lovely little country. My favourite place is Bled, nestling among the Julian Alps with a beautiful lake and lots of delightful forest walking trails. But I also like the cakes-and-coffee cafes in Ljubljana. Although it's the capital city of a sovereign country now, it still has the relaxed feel of a provincial university city in the Austro-Hungarian Empire.
Ha-ha! After writing that, I see that you live there, in Kranj! So you know!
