I'd prefer taking train and tram in Prague as opposed to taxi - public transportation is quicker and cheaper.
Metro is fast, clean, cheap a easy to use.
The tickets are now more expensive: 18 / 26 Kc - Czech crowns
How can I go from the airport Ruzyne to Josefsk'a 1, 11800 Praha by public transport?
Be sure to validate your ticket. We rode one stop, were asked by an inspector to get off the tram and were each charged a $40 for not validating. We were unaware of the validation process. We observed everyone else who got on the tram. We just did what they did. No one validated their ticket but we got the fine.
