Lisbon wasn’t originally part of our itinerary, but when we checked our map we realised it wasn’t far from Madrid, so we added it last minute. It turned out to be a great decision as it was such a beautiful city.
From Madrid to Lisbon it was a short 1 hour 15 minutes flight. If you are on a budget, compare flights on Momondo to find the best value. We ended up going with TAP Portugal Airlines. If you want to save one night accommodation you can choose to catch a sleeper train from Madrid to Lisbon instead.
Once in Lisbon, we caught the Aerobus into the city centre for €3.15.
