Fantastic place to stay for Barcelona. Nice appartment with everything we needed. Just around the corner from a street with many tapas/pinxos bars (eat at Koska, you won’t regret it) and 5 mins for the metro. You do have to climb the stairs but just think of it as working off all the jamon you’ve eaten. Carlos was super helpful, organized us a taxi from the airport and was there to explain everything when we arrived. Highly recommend.
