While I had read the reviews about location prior to booking, I didn’t really understand until our stay which was our first time in Lisbon. The apartment is in a residential area outside/north of the centre with most of the sites/areas we wanted to visit. While the apartment is about a 7 min walk to the red metro line, it is 15 min walk to the green line which is needed to get downtown. The red and green line do connect, but then it’s a longer journey on the Metro.
