Practicalities
Currency
Czech currency is called koruna, abbreviated CZK. For 1 EUR you get approximately 25 CZK. There are lots of currency exchanges offices in the city centre, however, proceed with caution. Credit cards (Visa and Mastercard) are widely accepted, usually even in small shops.
Electricity
230 V, 50 Hz with either Schuko or Europlug.
Tap water
Should be safe to drink, but you can confirm that at your hotel.
Tipping
There are no strict rules concerning tipping, but 10% is considered appropriate in a restaurant. There is no need to tip in a café/bar.
Safety
Language
Most (younger) people speak English to some degree. All shops/restaurants in the city center should have someone with decent English (or German).
Transport
Public transportation is very well developed, and we recommend using the metro and trams to get around. There are several variants of the tickets in Prague: 30 minutes (30 CZK), 90 minutes (40 CZK), 24 hours (120 CZK), and 72 hours (330 CZK). You can buy tickets all around the Prague. Please keep in mind you have to validate the ticket (stamp in the yellow box)!
Taxi
We recommend booking your taxi online (through your favourite app) or through your hotel, as to avoid any misunderstandings.
