The trip was great. Exploring Barcelona was very interesting. We stayed in Vildecans 20k outside of Barcelona. The public transportation was excellent we got a ATM card (Autoritat del Transport Metropolita) for ten trips and also the 5 day Barcelona Card. Both cards allow travel on the bus, the metro and the renfo.
I absolutely adore this city! It's sassy, smart and so, so Spanish! To me, it's like the perfect combination of the in-your-face NYC attitude and the elegance of Paris. There's so much to do and see ... it's really worth a visit!
