My friend and I had a great stay in Barbara's place. We only needed two double bedrooms, each with their own shower room and, despite Barbara's place also having two extra single rooms it was the best deal for our needs in the best location on Air BnB. That gave us the two extra single rooms just in case friends visited (which, given Barcelona's popularity was a good idea!). Overall the place was clean, stylish, functioned well (Barbara came willingly in person to resolve an electrical issue I had which was super kind) and, after the winter, I can imagine the terrace is also super useful. It's location, super central yet not actually in the old town is also perfect!
