I visited Croatia and Rijeka almost two weeks ago, yes, I made a mistake saying that Rijeka is a small city, honestly it seemed so to me, in fact it is spread over a very large area, also here I climbed very very many stairs (I don't want to see more stairs this month).
I have to admit it wasn't that cold, it was really great weather, the only minus was that we couldn't swim in the sea, the water was quite cold.
