The best thing about this AirBnB listing was the host (and her puppy Kuka). Marta was a welcoming and pleasant person. If you know some Spanish/Catalan, it will be much easier to communicate, but we managed despite not speaking each others' languages.
If you are sensitive to sounds (traffic noise, some neighbour sounds behind the wall) and smells (cigarette smoke, laudry detergent on towels), you may want to look for another place.
Because the place wasn't suitable to me, I decided to leave early. Marta was kind enough to accept the change I made to my booking after arriving, and thanks to her I got my refund for the remaining days that I cancelled. So although my stay was not ideal, I gave this listing five stars because of how Marta responded.
