The main thing I'm interested to know about Barcelona is what are the different districts like in terms of atmosphere. There's only so much google street view you can do really, so I want to hear where people stayed and what they thought of it. I am aware that most probably would have stayed in Gotico or near Las Ramblas or in Barceloneta. I'm not really interested in that, I'm thinking about finding a nice place in one of the outer districts like Eixample, Gracia or Sants-Monjuic where I'm going to get more bang for my buck. What were your experiences with the public transport system etc?
With Berlin I'm really interested to know if everyone just buggers off out of the city for summer, we will be there from early August so I am aware that people will be leaving to go on holiday. It would be a bit of a drag if things were a little bit dead. Although I do realise that in a city of 3 million odd people that's probably not going to be too much of an issue but would still like to hear some stories from people.
