Amazing place - big enough for a family to spend a few days - or a few weeks in Lisboa. The apartment is clean, functional, and in a fantastic old zone of Lisboa where you can appreciate the architecture.
The apartment is close to public transportation, and a ~$10 Uber ride to downtown or to the airport. There are plenty of restaurants around to eat, Lisboa famous "miradouros" (looking points) and plenty of street parking around.
Ricardo is a great host, everything was as advertised and gave us plenty of pointers and advice to make our stay more fun and enjoyable.
