Barcelona and Zaragoza day 2

Yesterday we arrived in Barcelona. The flight was short luckily, we took the bus, hailed a cab and we met up with Lukas, who is the owner of the apartment. He is a very nice guy and informed us about the city; the must-sees etc. The apartment is small but very clean, and it includes all the necessary equipment.
Today we decided to explore the city and play tourist, because it was too cold for the beach. We bought metro tickets for 3 days, and went to La Ramba, the most popular market street. Because it is Easter, most shops were sadly closed. We decided to buy tickets for the tourist Barcelona bus. It goes along with a monotone audiotour which caused great laughter. We saw the highlights of Barcelona, and after this we decided to rest in the sun; it had finally shown it's face! Then we took the metro to a good tapas restaurant where ate some great food (paëlla, rissoto, steak). When we finished, we went to the palace where a fountain was the protagonist in a light show! Many people gathered for this closure of the evening. Then we took the metro back to the apartment. It was a long yet interesting day.
