Surely there is no more beautiful city.
Here's my fact of the day, gleaned from cruising the Danube (which I have done twice - once in the day an once at sunset): they held a competition to design the Hungarian parliament building -and liked the designs that came 2nd and 3rd place so much they built them as well as the winner, on the same square. I just love that.
I spent a fair bit of the day on Margarite island, watching the dancing fountains. It's like a never-ending firework display (without having to crane your neck). Then every hour on the hour they play some music and the fountains perform a routine to it.
This is my most southerly and easterly point: tomorrow I head north and west. By train! Exciting, and a little bit sad.
