I had a great time at Ana's place! Central but quiet and well connected by public transport, ideal to get around the beautiful city.
The flat is actually more spacious than it looks on the pictures (rare but true!) and the small balcony is very enjoyable. Lots of space to sleep with a well-sized bed and big sleeping couch.
Personally, I wanted to add that this flat is good for people who physically struggle with steep hills or stairs (both very common in Lisbon), since the flat has an elevator and is located between the many hills. Looking forward to returning!
