Purpose Airbnb is the peer-to-peer (P2P) accommodation platform that has attracted researchers’ attention during the past decade. The purpose of this paper attempts to illustrate the scarce research on P2P accommodation platforms other than Airbnb and to highlight the research gaps concerning these platforms. Design/methodology/approach This study starts by presenting a literature review on Airbnb based on several review papers about P2P accommodation sharing and conducts a quantitative comparative analysis between existing literature on Airbnb and other P2P accommodation platforms in Web of Science (WoS) using a keyword search. Findings Findings suggest that the literature regarding P2P accommodation platforms other than Airbnb is limited and that little is known about their possible impact on the collaborative tourism ecosystem. The analysis also suggests further research on P2P accommodation platforms to move on from an Airbnb-centric view and include other types of P2P accommodation platforms. Originality/value This paper compares the most common topics studied regarding Airbnb and other P2P accommodation platforms, highlighting the existence of other for-profit and non-profit accommodation platforms. It proposes new lines of research on different types of platforms such as the niche P2P accommodation platforms.

Value co-creation, in the sharing accommodation sector, has been extensively analyzed but mainly with Airbnb as a reference and focusing mostly on guests’ perceptions. The aim of this study is to analyze the value co-created for users (guests and hosts) in the non-profit sharing accommodation platforms Couchsurfing and HomeExchange. This study also aims to analyze whether the co-created value of these platforms differs from that of for-profit platforms, along with how the outcomes, resources, and practices of the value co-creation process can help create wellbeing for individuals involved in the accommodation experience. Given that most of the existing literature on value co-creation in sharing accommodation platforms is based on Airbnb and guest perspectives, this study is a pioneer in analyzing how guests and hosts co-create value in the context of non-profit accommodation platforms using online travel reviews (OTRs) from non-profit platforms, and how the co-created value contributes to the wellbeing of the individuals involved. Results show that a set of tangible and intangible resources, such as the home and its amenities, helps users on non-profit platforms co-create value and that interaction and social practices between guests and hosts help co-create value for both groups. This implies that non-profit accommodation platforms may contribute more to the social dimensions of wellbeing of their users than for-profit platforms such as Airbnb where the host is typically absent from the experience. In addition, this study demonstrates that the co-created value in non-profit platforms depends on the modus operandi of each platform. On Couchsurfing, guests and hosts co-create more value from their social practices, and on HomeExchange, value co-creation depends more on tangible and intangible resources.
