Airbnb has bought a British travel website designed for tourists with disabilities.

Accomable, which was founded two years ago by two entrepreneurs with spinal muscular atrophy, has been bought by the US company for an undisclosed sum.

It works in a similar way to Airbnb, allowing homeowners to rent out rooms or entire properties to tourists on a short-term basis, but only showcases rentals with step-free access and other accessibility features.

After the deal, Accomable's listings will be merged with Airbnb. The company's team will move to the Airbnb office in the UK and its chief executive Srin Madipalli will relocate to San Francisco, in the new role of product manager for accessibility.

Airbnb, which has grown to become one of the world's most valuable private tech companies, does show listings that are suitable for disabled guests, but Accomable allows users to filter listings in greater detail.
