Javier's place is pretty damn magical. Its incredibly convenient for tourists and professionals. Easy access to the Metro, Taxis, and the hop on hop off sightseeing buses. Walking distance to Font Mágica and the MNAC.
Oh, and then there's the terrace. Yeaaaah. Perfect for those warm Barcelona nights. Javier was very responsive and supremely helpful.
And one last thing... The tap water is fine. Drink up.
