Is there any architect or architecture enthousiast around here? I have couple of questions to ask, i.e. Is there any possibility to visit construction sites of "campus de la justicia" and "centro internacional de concenciones" and are they worth to visit or still in an early stage? Additionally, as far as I understand, the public transport is not well settled in the far north of the city, so would you recommend to rent a car (I don't have any idea about Madrid traffic) or is there other recommendations ? What about the car with a driver , how much would that cost approximately for half a day, approximately?
