Bruno's apartment is literally in the center of Lisbon. Everything is within walking distance. It is perfect for a city trip in Lisbon with a big group where you are out all day and quickly back home in the evening.
On that note I would like the add that earplugs might be quite useful for those who go to bed early and have a light sleep because the tram is actually a bit noisier than we expected.
Still a great place to stay in Lisbon.
