What a great apartment in the perfect location! Just out the door is a walking street called Carrer de Blai. It has the best Tapas (Pinchos) in Barcelona - all 1€ a piece. I almost didn't want to explore Barcelona because it was just so easy to eat cheap pinchos and drink little cañas all day. And the apartment was right next to Poble Sec Metro stop so you could get anywhere, including the airport easily. We had a fantastic time.
