The room is located right in lisbons heart, so there are short ways to quite everywhere and it's not on a hill, simply perfect.
Anyhow, for some reason we didn't got the room pictured above but another in the flat, which was about the same size. There are three Airbnb rooms in the apartment, if they're alle occupied the bathroom might get busy.
Only minus: no heating at all. We've stayed there in the end of march and at some points it was pretty cold.
