Exactly as described, and then some. Such a lovely, cozy place, with thoughtful touches. Mornings in particular were delightful — quiet, sunny and filled with great Lisbon light.
The window and little balcony are over a pedestrian street full of restaurants, so no traffic noise, just the pleasant murmur of crowds. (And since restaurants close around midnight, you'll sleep like a baby.)
Personal tip: don't go to the restaurants on the main drag, but almost any of the tiny hole-in-the-wall joints on the side streets are no-frills excellent. O Marques was a favorite among those, and Pinoquio among the bigger ones that look like they may be tourist traps.
