We need to get from near Sol metro station to Terminal 4 at Madrid airport on the Monday after Easter (April 10) for a 1:30pm flight to Heathrow. Not sure if metro line 8 or cercanías train C1 is the best option with luggage. We will have one rolling bag, one carry on backpack and two small day packs. Not keen on stairs which the Madrid metro seems full of and looks like we need to change twice to use metro line 8.
i am inclined towards metro to Atocha then change to C1 train but am having trouble working out the frequency of C1 trains. Any suggestions for the best option?
