Alexandra and Pedro have a great spot right in the historic Alfama district. It is well located with easy access to public transit and within a 20 minute walking distance of the main downtown area. Note that if you Uber/taxi to here, you will have to be dropped off a few streets away as many parts of the Alfama are pedestrian only. The place itself is lovely, modern, and had great amenities including espresso and a bottle of wine. One note to those travelling during festival season (e.g., early June), a large part of the celebrations take place in the courtyard directly outside this location, so if loud music that goes late into the night is an issue for you, make sure that you check the festival schedule for Lisbon. The plus side is that you can really get immersed in the culture of Lisbon with cheap bifanas, grilled fish, sangria, and ginjinha! The non-festival nights were very quiet. Would definitely stay here again.
