  In recent years, what has become known as collaborative consumption has
undergone rapid expansion through peer-to-peer (P2P) platforms. In the field of
tourism, a particularly notable example is that of Airbnb. This article
analyses the spatial patterns of Airbnb in Barcelona and compares them with
hotels and sightseeing spots. New sources of data, such as Airbnb listings and
geolocated photographs are used. Analysis of bivariate spatial autocorrelation
reveals a close spatial relationship between Airbnb and hotels, with a marked
centre-periphery pattern, although Airbnb predominates around the main hotel
axis and hotels predominate in some peripheral areas of the city. Another
interesting finding is that Airbnb capitalises more on the advantages of
proximity to the main tourist attractions of the city than does the hotel
sector. Finally, it was possible to detect those parts of the city that have
seen the greatest increase in pressure from tourism related to Airbnb's recent
expansion.
