This article focuses on the process of cosmopolitan learning among hosts in a hospitality couchsurfing network in Siberia. The data making up the empirical basis for the study were collected during fieldwork in Siberia: between 2007 and 2011 in Krasnoiarsk and Novosibirsk and from 2010 to 2012 in Irkutsk and Vladivostok. The article argues that the interactional dynamics between hosts and guests in cosmopolitan learning are determined by the combination of emotive and cognitive rewards. The primary emotional charge occurs as a result of the first interaction with the visitor, while a cognitive “bonus“ is represented by the opportunity to practice a foreign language in the home environment. In addition, hosts reflect on such aspects as the exchange of lifestyle ideas, the exposure to everyday habitual practices, and the realization of commonality and difference. These reflections leading to self-discovery in the comfort of one's own home constitute an important element in the process of cosmopolitan learning.
