Francisco was an excellent host with fast communication. The apartment is within 10 minutes walking distance of Font de Montjuic which has a light show to music in the fountain in the evenings, worth a visit.
The apartment is easy to get to, I took the Aerobus from just outside the airport to PLAÇA ESPANYA, from there I walked to the apartment. There is a nearer metro stop if you do not fancy the 10 minute walk.
