Our first night in Barcelona happened to be the night of UEFA Soccer Finals game between Real Madrid Atlético Madrid. We watched the game live with our AirBnb hosts which was really fun. The game was being played in Milan (where we had been a week prior) and we had seen a bunch of advertisements for the championship game while in Milan.
First things first was to rent bikes. Barcelona has great public trans, but is also very bike friendly. We rented from a shop in the Gothic Quarter called Green Bikes. Then we set off to explore this very touristy area.
