Lisbon is a beautiful city, very cheap according to Northern European standards, full of life, color and wonderful restaurants.
I stayed in the Zuzabed B&B; a great place, dead centre, with very friendly personnel. They will plan your sight seeing, walking routes, restaurants etc. for you. Just get there and they will arrange everything for you during the wonderful breakfast…. They have several rooms and a separate apartment.
Great neighborhood restaurant, incredible food: Cafe Buenos Aires is very conveniently located opposite the Zuzabed B&B!
Great lunch places:
Lost In and Noobai
Cascais beach is nice to go in a 30 minute train ride along the coast. Have lunch at World of Wonders
Just walk through the old quarters of Lisbon and enjoy the sights, sounds and smells….
