Romi & Gabriel were great hosts when me and a friend came to stay in Barcelona for Primavera Sound festival. The space is shared with them, but that just means a shared entrance and kitchen - everything else is private and it still feels like you have your own space.
Location is ideal for a city stay (a bit further away from the festival site but worth the trade-off). There’s an incredible bakery basically next door and some great local bars and restaurants.
Would definitely recommend if you’re looking for a stay of 1-2 weeks, we had everything we needed in walking distance too.
