Hi there! We are heading off to Barcelona at the end of September and staying at the Hotel Oasis (Calle Pla De Palau 17) which is almost beside the Barceloneta Metro. But it doesn't look like there is a direct metro line to Barceloneta station from the airport or the Placa Catalunya.
I had thought of the train to Placa de Catalunya and then walking to the metro at Passeig de Gracia and taking it down from there.
Can any of you good people tell me if that is the easiest way (I want to use public transport rather than a taxi) or whether I have missed something obvious?
