Sarah and Pedro's listing was beautiful. The apartment was spacious and the bedroom had a lot of light. It is also situated near grocery stores, pharmacies, and restaurants. If you are looking for a non-tourist view of Lisbon, this area is good for you. Sarah and Pedro are also very responsive to questions so don't be shy to ask them questions if you have an issue.
Please note that using an uber, metro/bus, or walking is probably your best option because local taxis are hard to flag down.
If you have an aversion to elevators like myself, you may not like this one because it is quite old. I opted to walk up the 5 flights every-time and didn't enter the elevator once.
I would recommend this stay.
