We have tickets to Bruce Springsteen at Synot Tip Arena and are looking for advice re public transport options from Prague Centre and return. We are staying in New Town; close by to Karlovo Namesti metro station. We would value advice re the best / simplest public transport route from there / that area (or thereabouts in the city centre) to and from the Synot Tip Arena. Is public transport generally safe at night returning from there to the city centre? I expect there will be a lot of other people doing the same.
