I think it is a very good place to stay in Lisbon. The apartment is very clean and comfortable in a great location in the center of Alfama. Very easy way to get to the airport even at night. (30 minutes by metro, 16 minutes by taxi).
There is a train station and a metro station nearby. Many restaurants, cafes, shops and a supermarket 3 minutes from the house.
Carlos is a very nice, funny and helpful man. He recommended tourist attractions and good restaurants. Contact with him was very simple and he cared for us.
I will choose this place again if I return to Lisbon again,
