Adolfo Suárez Madrid–Barajas Airport

If using Madrid airport there are "satellite " terminals that access to/from is very long and when we arrived in the evening there wasn't an operating lift to get to the train that links the terminals. No information at all just waited and eventually a wheelchair enabled van arrived to take us to main terminal to get a taxi. The train has wheelchair access as we used it for return flight (morning flight) but there seemed to be a problem with the lifts in the evening - take it there are stairs & escalators but at night no lift access. The worst designed airport I've been in. Be aware if you are using Madrid airport.
