We loved so much to stay at Humberto's place. He has a modern flat with well thought details (loved the bath interior and door!). But the best of everything is the host himself: Humberto!! He is a kind person and made such a warm welcome. He gives you the best hints about Lisboa and surroundings and he provides you some great tools/how-to's for travelling better across town and surroundings (where to park, drive, metro tickets etc.). As being a born Lisboa he knows the city better than his back-pocket. If you cannot stay at his place, you should at least book his walking experience of Lisboa. You will not regret this!
