You might want to wash your shoes off.
I've been in that square and you don't want to catch any of my only-tolerate-cute-chicks-and-not-ugly-hogs-who-will-take-the-four-dollars-you're-paying pathogens. It could end your career.
Did you take a walk to that wide boulevard from Wenceslas Square that goes uphill to the museum? Glorious views!!
Have you been to the old Jewish quarter and seen the clock that runs counterclockwise with Hebrew/Yiddish characters?
Or walk the Charles Bridge?
I stayed at the Don Giovanni which, though near buses and the metro, is WAY out of town. It was near the new Jewish cemetery, however, which made for interesting siteseeing.
My last day I actually walked from the east side of Charles Bridge to where are, at the astronomical clock, to Wenceslas Square to the museum and back to the hotel.
BEAUTIFUL city.
