We were very happy with Alfama and the apartment. It was clean and comfortable with lovely views over the river Tagus.
Alfama is a lovely area with lots of bars and restaurants and little shops were to get food and souvenirs.
We felt very safe and people were very friendly. It was very easy to get from the airport to Santa Apolonia train/metro station and then only 5 minutes walk to the apartment.
One point we need to make is that the apartment is not suitable to people with mobility issues.
