The photos of this apartment absolutely do not do it justice. It is spacious and airy and stayed cool even with the aircon off while we were out all day. The host was very helpful and responsive to messages, helped us arrange a taxi from the airport and check in was very easy.
However the best thing about it was the location - the area has such a great vibe, tonnes of gorgeous bars and restaurants, a lovely buzz from dawn until late but not at all rowdy and easy walking distance to the beach/gothic quarter/Las ramblas. Also very close to 2 metro lines.
Overall absolutely fantastic.
