Spoken languages: Polish is the official language but English is widely spoken in the city.
Local habits and customs: Tipping is customary, with 10 percent considered standard in restaurants. Traditionally, visitors to Polish churches are expected to dress modestly – no shorts for men, no bare arms for women. It is considered rude for visitors to look around churches during Mass.
Currency: The currency is the Polish złoty (PLN). Credit and debit cards are accepted almost everywhere, but it’s a good idea to carry some cash for smaller shops or market stalls.
Getting around: Warsaw operates an integrated bus, tram, metro (two lines) and SKM suburban train network, with ZTM tickets valid for all four modes of transport. Tickets (bilety) can be bought from any newspaper or tobacco kiosk sporting the “MZK” logo, from ticket machines at some central stops, and inside most trams, buses and overground trains. Single-fare tickets valid for any journey lasting up to 75 minutes cost PLN 4.40; a 20-minute version costs PLN 3.40. It’s more economical to buy a 24-hour pass (bilet dobowy; PLN 15).
Electricity and plug types: Poland uses standard European 220-volt power with two-pin plugs. UK travellers need a continental adaptor.
Time zone: Poland is on Central European Time, 1 hour ahead of GMT, and observes Daylight Saving Time.
Required travel documentation: UK travellers only need a valid passport for trips under 90 days, with no visa required.
