Ana is a great host. Our plane was late but she waited patiently and was kind enough to let us leave our bags for a couple of hours till our plane left.
The apartment is light, airy and well equipped and furnished with great taste. It's opposite a great bar (which has nice food) and a neighbourhood restaurant (very popular). Just around the corner is a pizza restaurant which was also great. It's just 5 minutes walk from one of the main squares so location is great. You do need to walk up a fairly long flight of steps to the apartment so it would be difficult for anyone who had limited mobility, but then Lisbon is very hilly almost everywhere.
We would recommend the apartment.
