Our favourite aspect of the apartment was the location, with a market showcasing the best of Portuguese food and Sangria right outside the door, a short walk to pretty much any point of interest in Lisbon, and easy access to local and regional transport (for example the trains for Sintra depart from a station nearby).
The apartment itself left little to be desired, clean and comfortable, though we spent most of our times in the streets, restaurants and pubs around the city.
Great spot if your looking to make the most out of a shortish trip to Lisbon!
