I had a great time at Sarah's place. Very clean room and bathroom. I liked the independence and privacy. It is not located in downtown Lisbon, but if you like walking as I do, it's not far from the main touristic spots, 30 minutes or so. If you prefer avoiding the hills of the city, you'll find choices for public transportation nearby. And Sarah was really kind, she's a great host. I'd come back there with no hesitation.
