I'm flying into MAD T4 in a couple of weeks, and will need to get into the center—I'm staying between Plaza Mayor & Tirso de Molina. I'd rather not deal with the shutdown of the Metro's line 8, so looking at taking cercanias into town. I'm trying to figure out my "last mile".
Can I easily, without exiting and reentering the system, change cercanias trains at Chamartin or Nuevos Ministerios, switching to a train that would get me to Sol? (I know the walk from Sol to my accommodation.)
Alternately, I think I'm looking at cercanias + metro, either to Atocha and switching to Metro line 1 to Tirso de Molina or to Piramides and Line 5 to La Latina.
I'm unfamiliar with all of these changes, so looking for what would be smoothest/easiest at morning rush hour with a rollaboard and a rather large backpack.
