what is the best way to transport from the airport to the train station in Madrid? We have t.5 hours. Would a taxi be exorbitant? Thanks.
If you have only 1.5 hours you will almost certainly have to take a taxi, especially if that time includes baggage collection. Be aware that there are 2 main train stations and you need to know which one you are leaving from.
if you have an hour and a half from landing til your train leaves, take a taxi if you need to collect luggage or go through customs. otherwise, the metro is best, if you're flying in from within the EU and only have carryons.
