Does anyone in Prague speak English or any other language?
Most Czech people, especially those in touristic areas, speak enough English to give you what you need and many speak it fluently. German and Russian are commonly spoken, especially amongst older Czechs and sometimes other languages. English is becoming recognized as the standard and Czechs are learning it to keep up. As always, when travelling, try to speak clearly and slowly.

Are Czech taxis safe or are they, as I've heard, all sharks?
There are plenty of safe taxis but it pays to be aware that they will take advantage of you and charge as much as they can. Try to avoid flagging down taxis in the street, especially in touristic areas. Try and set the price before getting in, and don't fight if the situation becomes threatening. All drivers should use their meters, if they do not, they are definitely trying to rip you off. We recommend AAA taxis which can be called at tel: 14014 or City Taxi on 257257257.
