The location makes it the perfect place for discovering Lisbon within a 2-3 days stay. and don't miss out a breakfast with a view on the terrace (tip: the pastelaria just above in the street does the trick with fresh pastel de nata, great croissant and fresh orange juice). Checking was super simple, the host super nice. I would only advise a deep cleaning and refurbishment of the bathroom joints to remove moist and be at the standard expected for such price range.
