Charming little flat in (as far as I am concerned) one of the best parts of Lisbon - everything in walking distance, including the great estrela park, but far enough from traffic to be quiet at night. Floors are a bit noisy so you can hear the upstairs, but that’s quite usual in old Portuguese houses.
The outdoor area with its two trees is fantastic for breakfast - I think I spent more time out there than in the flat :-)
