Gap: One potential gap for Airbnb is the lack of accessibility options for guests with disabilities. While some hosts may have accommodations for guests with disabilities, there is no way for guests to filter their search results based on accessibility options.

Solution: Airbnb could implement a feature that allows guests to filter their search results based on accessibility options such as wheelchair accessibility, grab bars in bathrooms, and accessible parking. Additionally, Airbnb could provide resources and guidelines for hosts to make their listings more accessible for guests with disabilities.

Summary: While Airbnb has made strides in providing personalized experiences for guests and hosts, there is a potential gap in accessibility options for guests with disabilities. By implementing a feature to filter search results based on accessibility options and providing resources for hosts, Airbnb can improve the experience for all guests.
