Spoken languages: French, German and Luxembourgish are the official languages. However, English is widely understood, especially in tourist areas.
Local habits and customs: Luxembourgers are known for their politeness and reserve and are pretty laid-back. Greeting with a handshake is common. Tipping around 10 percent in restaurants is standard.
Currency: Luxembourg uses the euro (€). ATMs are widely available, and credit/debit cards are accepted almost everywhere. It's handy to carry some cash for smaller establishments and tips.
Getting around: Luxembourg has an efficient public transport system, which includes buses, trains and trams. Public transport is free for everyone, making it convenient to explore the city and beyond. The Old Town in the centre of Luxembourg City is best navigated on foot, or for longer trips, consider renting a bike from one of the many bike-sharing stations.
Electricity and plug types: Luxembourg uses the standard continental European plug (Type C and F) with a voltage of 230V. UK travellers will need an adapter.
Time zone: Luxembourg is in the Central European Time Zone (CET), 1 hour ahead of GMT and observes daylight saving time.
