We enjoyed our 5 days in Lisbon and at Pedro's house. Central place in the middle of a lot of restaurants and cafe's. Pedro was ver helpful with his pre-travel advises about arrival to Lisbon and transportation to apartment. We had no problems during our stay. Best way for the directions to the apartment is this: If you are coming with a taxi or uber, tell the driver to drop you in front of Autoridade Tributaria e Aduaneira. When you get off in front of this building, just go across the street and keep directly from the narrow street. It will directly take you up to Igreja de Sao Miguel which means you are at home :)
