The Birds apartment is located in the centre of Lissabon, a prime location and always easily findable since it's directly next to a cathedral. The building is old, so expect some doors to creak, potentially waking up somebody in the other rooms when you open them at night. But that's the only small downside really. When you close the windows you almost wouldn't realize you're in the centre, since they isolate the sounds well and you can make the bedrooms really dark by closing the window shutters if that's your thing. The host was super helpful and we had a great time in Lisabon; would recommend!
