Okay, before you go "ewww, gross....." I have to say that the streets of Bratislava are quite walkable barefoot. Not all places, not every time, but it's doable. And come on, on the picture it actually looks romantic :-)
I think I did it once too - different city, different time, different reasons - only I couldn't wash it off for about a week :-)
Have a great, sunny long weekend!
