House Sitting. While travelling many people use house sitting as a form of accommodation. It is free accommodation while you get to live in the comfort of a house. This helps keep the costs of travelling lower than other traditional accommodation types. House sitting involves an agreement between the house sitter and the home owner that the house sitter will occupy a house while the home owner is away. Generally the house sitters will be responsible for minor household responsibilities (e.g. keep house clean, bring in post etc). Often House Sitters will also need to care for the home owners pets as part of the agreement.
