Helene's AirBNB was ideal for our quick one-night stop in Barcelona: it is affordable, clean, and right in the middle of Barcelona's older districts, with lots of things to do within a walking distance. Helene was super friendly and quick to reply, making our arrival & stay very smooth. The area around the AirBNB is a little noisy though, so if you're a light sleeper I would definitely recommend bringing some earplugs to get some sleep :) Other than that, I really recommend this place !
