Finnish is the primary language, but many locals also speak English, and Swedish is also common. One of the first phrases I learned in Finnish was "Kiitos," (Say it Ki-i-toes) which means "Thank you." While Finns are very polite people, they tend to show their politeness, rather than say it. There is not really a Finnish word for "Please"!
In Finland, the euro is used. One euro is worth about $1.18. While most places in Finland will take cash and coins, most Finns pay with credit or debit cards.
One of the cool things about using the euro is that it works in nineteen different countries, including Ireland, Italy, Germany, France, and Estonia, to name a few. You can travel to any of these countries, and use the same type of money.
In Helsinki, prices are higher than in much of Finland. A bottle of water usually costs about 1-2€, although it can cost more in tourist areas. If you are eating at a buffet or in a cafeteria, though, tap water is often included with the meal.
