A guest house is a separate space from a main home that provides accommodations for guests, family members, or even renters. A guest house can range in size from a small 200 square foot studio with a kitchenette to a large two-bedroom, two-bathroom space with a full-sized kitchen, living room, and dining area.

A guesthouse is a small building, close to, but not attached to the main house on a property. it functions in the same way a guest bedroom does, and in some cases has has full kitchen and living areas.

A guest house, sometimes referred to as a casita or in-law suite, is a separate living space located on the same property as the main house. Typically, it functions as a self-contained accommodation, complete with a bedroom, bathroom, and sometimes a small kitchen or kitchenette.

The owner most often lives in the guest house, or on the property in a separate dwelling. Guests can be any age, but some younger travelers prefer the lower prices of hostels. Guests are primarily international travellers - individuals and couples - not large groups, families in general, or large families specifically.
