Great area for an authentic experience in the old town and very walkable. The apartment is lovely and just as pictured.
Note to fellow travelers that the bed is full sized (slightly larger than a twin) so it would be a better choice for couples or a single person. As two women, we found it snug so one slept on the couch. It's also easy to hear the neighbors in the morning so it'd be best for early risers.
Overall a nice place and we loved Lisbon!
