We stayed in Javier's apartment for 5 days - transport connections (airport via the A1 bus, beach via the D20 bus and centre of town via the metro) all on the doorstep. The balcony was lovely for sunny breakfasts, and you can watch the magic fountain on Montjuic from there Thurs-Sun at this time of year. The apartment was very well-equipped with excellent wifi, dishwasher, washing machine and even a safe.
