Coimpact Coliving is one of the best experiences I ever had in hostels/shared spaces in Airbnb. The place was always under control in terms of cleaning and organization. Sam and Fernando were in charge of the place during my staying and they were always happy to help. The price was very fair, and the location was perfect if you are looking for a centric location to explore Barcelona. Keep in mind that you need to share your space with a lot of people (from all over the world) so be patient and enjoy your stay.
