Unfortunately I dod not have the chance to meet Joao but he is very kind and easy to communicate with through the airbnb app and phone. His place is just outstanding. It is well situated and has all comfort you can ask for. Next door there was this lovely couple who checked me in and to whom I could ask all questions if needed. They are extremely kind and I felt really home being there for a week. If you wish to explore Lisbon to the fullest while being in a cosy, charming, place in a calm neighborhood, yet not too far from the busy centre: You are in the right place :)<3 Obrigdo.
