Where to go after-hours?

Plaça de Catalunya & El Barri Gòtic

The quarter is the centre of the old city of Barcelona, built primarily in the late 19th and early 20th century, though several buildings date from medieval times. The Barri Gòtic retains a labyrinthine street plan, with many small streets opening out into squares.
It stretches from Plaça de Catalunya to the marina (near the seafront), edged the famous La Rambla street.
How to get there: Bus Lines L94 / L95 ( 15 minutes direct )

Platja de la Barceloneta

This beach is inextricably linked to the fishing quarter of the same name, Barceloneta, Barcelona's classic neighbourhood by the sea, where the people of Barcelona love to come and eat fish and seafood dishes and "tapas".
Within walking distance from the above Barri Gòtic and La Rambla street (across the marina).
How to get there: Bus Lines L70/L72/L80/L86 changing with D20 at Plaça Espanya ( ~40 minutes 2 bus lines )
