Marcos was nice enough to meet us at the R2 train station (direct route from the BCN airport) which is a few minutes away walk. The apartment was good as per the description. It had everything you need for a comfortable stay. Bus and tram stations in front of the apt. building. Carefour and shopping center across the street. Very convenient. The host provided directions to all the major attractions and other interesting things to do.
Overall I am satisfied.
