All host families are different. Some have children, others do not. Some are religious, others are not. But they have one thing in common. They want this to be the best year of your life!
Your host family is responsible for you throughout your stay, so they set the rules, like when you should be home and what you are expected to help with around the house. They will provide your food and living expenses. Other costs such as hygiene items, bus passes, leisure activities, travel, clothes and more are your own responsibility.
