Carla & Joel were super responsive, every time I contacted them, they reply straight away.
The house is located in a private road that only residents with permission can enter by car. It is located on hills going up and down, with a tiled sidewalk.
On our the last day, after going up the hill with our bags, to wait for our uber to head to the airport. The uber driver told us that TAXi are allowed into the resident area, it was a big disappointment.
But I hope this information can help, for the next person who stays in the property.
Call the local taxi and they can pick you up right near the address.
The house in general was OK.
The cleaning was not the best, I sent some pictures to the owners and they are aware, will do best for the next one, there is only one window, and it smells a lot!
We left the dehumidifier on, but the musty smell was always strong.
The location is very good, in the middle of Alfama, 5min walk from the Santa Luzia viewpoint, 15min from the center of Lisbon
