My stay was very pleasant at Ana's place. The house is located in a historical district in a quiet street (although close to the metro station Anjos), and the room was very quiet as well. They have a cat called Kiko, who essentially belongs to the flat, and he is very charming! Ana is a very nice person whom you can easily have a chat with and ask for her advice with regard to your stay - make sure you check out her Lisbon guide! She was very flexible with both check-in and check-out times, which was a helpful advantage for me.
