Hi been to Barca many many times, as I used to work in northern Spain flying into Barca airport, fly to BCN Barcelona, it's about €30 fora taxi to the Ramblas and this is a fantastic place going down towards the sea,loads of street performers, some are unbelievable, loads of stalls all the way down and some nice hand made jewellery at the bottom keep her sweet after the Ramblas you can visit the aquarium place or the Barcelona Zoo this is a good setting point oh yer flights are easy to get also and very well priced
