I lived in Barcelona and come back to visit several times a year so I have stayed in many Airbnb’s. This has been my favorite to date, this location is in my opinion the best in the city. You are staying in a less touristy part of Eixample but still very close to everything, right in the middle of Passeig de Gracia, Sagrada, Arc de Triomf, and Psg San Joan. The apartment itself is the perfect mix of historical Eixample charm with all of the modern touches that you would want. I would highly recommend.
