Many thanks @karizma, I really appreciate it. To tell you the truth, when I was preparing this post, I had to go to the fridge myself 😋. Yes, I agree with you, it was really crowded. At least we didn't stand still, we could still walk slowly through the streets. Restaurants and bars were busy in the centre, so we also went to the ones a little outside the strict centre. We expected the crowds, though, because we were there during Halloween and All Saints' Day. At first we were a bit shocked by the crowds, but then we got used to it. We just went with the flow, a few crowds didn't spoil our trip.
