Had a great time at Lisbon and Elsa's tips for the city are great! The flat is located in the Belem district with some really nice POIs. Downtown is just about 10 minutes with the public transportation. The falt itself is really well equiped with all the things you need. Its also perfectly located to start some day tours around Lisbon like Sintra or Cascais. I can only recommend Elsa's flat and would definetly go there again if I ever get the chance to visit Lisbon again!
