You stay in Jorg's place for one reason and one reason only: the view.
Otherwise, the apartment is perfectly serviceable and accurately described. It wasn't as clean as we would have liked (dirty glasses in cupboard, dusty bathroom), but we managed just fine.
For an extended stay in Barcelona there are other neighborhoods I would pick. But for a few nights and that amazing view of Sagrada Família, Jorg's apartment delivers something you just can't get anywhere else.
