Revealing Airbnb user concerns on different room types

Airbnb, one of the most successful models in the sharing economy is considered as a major disruptor to the lodging sector

(Dolnicar, 2019). Prior literature suggests that the success is contributed by the unique experience Airbnb brings to its users, which is considered different from traditional hotel experience (Hajibaba & Dolnicar, 2017; Tussyadiah & Zach, 2017). Therefore, understanding what do customers look for in their Airbnb experience is of great importance. A few empirical studies investigated the research question but received contradictory conclusions: the areas that Airbnb users care about are found vary in different studies (Brochado et al., 2017; Guttentag, 2019). The reasons might be attributable to the limitation of research data and lack of consideration of the difference in Airbnb accommodation types. Many existing studies evaluate Airbnb users' experience by analysing data collected from questionnaires. This type of data is useful but might be subject to the incomplete limitations as questionnaires only encompass a limited pool of Airbnb users who opt to participate (Zhong et al., 2019). Moreover, existing research analyse Airbnb users' online reviews as a whole package without considering the

difference in users' experience triggered by accommodation types (Cheng & Jin, 2019). Users who choose different types of accommodation may have different needs. A recent research (Dolnicar & Zare, 2020) predicts that the outbreak of Covid-19 might cause a reduction in the supply of entire homes, forcing Airbnb move back towards sharing of spare rooms. It becomes essential for Airbnb hosts to understand user experience and concern specifically on the latter accommodation type in order to build up competitive advantages and achieve market success in the post-Covid world. Therefore, in this research note, we investigate how the areas that Airbnb users concern about vary across different types of accommodation by analysing their reviews online
