One of the best European cities
After visiting, Lisbon is now one of my favourite cities I've been too. There's so much to do in this city, as well as nice places to visit like Sintra and Cascais which are both a short distance on a very cheap train journey away.
Insider Tip:If you go to Sintra, go early in the morning so you have a whole day there as there are so many different things to see there. Also if you go to cascais to rent out the free bikes go early too as they quickly run out.
