Spacy flat close to Avenida da Liberdade. Lots of small shops, cafes and restaurants around. Within walking distance to most attractions of Lisbon. Beds are comfy and the environment is quite. We didn't encounter the noise from above (which some reviewers mentioned) cause there was no one above.
However, there was a moist problem in the appartment which is surprising at the end of the dry season. Moreover, the patio is an opportunity missed since its designed and maintained without love. If both these issues are addressed (or don't matter to you) its a great place.
