Airbnb knows its hosts haven't always been kind to people with disabilities, and it's taking some definitive steps to fix that weakness. The company just bought Accomable, a startup that helps you embark on disability-friendly travel. While Accomable is winding down over the months ahead, its accommodation listings will find their way into Airbnb's entries for over 60 countries. You'll know if a host really does have accommodations for disabled guests throughout the home, not just wheelchair access at the entry. Also, Airbnb is pursuing its own improvements to help you make more informed choices.
