What is the best to travel from Madrid to Lisbon? I used to use train but it stopped on the way and very cold indeed.

The train is areliable, but check out iberia.com and the special last minute offers (they come out on Thursday). they regularly have Lisbon for 115 euros – and you're there in an hour. In fact with the time difference you arrive at the same time you leave Madrid.

I know this bus route was/is covered by the http://www.Movelia.es website. Unfortunately, it's only Spanish but you should be able to figure it out. Good luck!
