Currency: Although Poland is part of the European Union, its currency is not the euro, but the złoty (PLN). It is advisable to change money at exchange offices ('Kantor') in city centers rather than at the airport, as they usually offer better rates. Payment by card is very widespread.

Internal Transportation: The train network (PKP) is an efficient way to move between major cities. For more specific or economical routes, the bus network is very extensive. Within cities, public transport (trams and buses) is efficient and easy to use.

Language: The official language is Polish, a Slavic language that can be difficult for Spanish speakers. In tourist areas, hotels and restaurants, it is common to find English-speaking staff, especially among young people.

Tips: In restaurants, service is usually not included in the bill. If the service has been good, it is customary to leave a tip of around 10% of the total. It is not common to tip taxi drivers, but you can round up the rate.
