Nice spacious apartment closer to public transport. The host was very responsive to questions.
Ideally a place for 2 as the sofa bed wasn't very comfy. One tip for people traveling to the apartment from airport, take the train to Av. Tibidabo and not Vallacarca. The latter is an uphill journey and it was a tough one. Learned from experience :). Also, the apartment is 30 mins from city centre. Overall, a good first experience in Barcelona.
