I stayed for three weeks in February and March 2021.
The terrace is great. Large enough for four seats at a table plus a rocking chair. Views of the bridge, Cristo Rei and the Padrão das Descobertas (all illuminated at night) and the river. I sat there as much as l could.
Juliette the host was friendly and particularly engaged. She was on time for check-in. During my stay she was caring, for example offering and delivering an extra heater and going so far as to buy a drying rack because of my hesitations about using the clothesline.
The building is on a lively high street which has a bio supermarket as well as a traditional food market. Most of the motor traffic does not pass the section where the building is. There are bus services nearby. There is easy access (20 minutes on foot) to the river and to the Monsanto forest.
It looks like the photos. The decor is light, though note that the windows are skylights. Attractive heavy china plates. You'll need to take care in places because of low inclined ceilings, low doors, narrow door to terrace (if you do not unbolt the second door), and a step to the terrace.
Things generally worked: wifi, hot water (though even for one person it could run out if one lingered too long in the shower), shower, both heaters, kettle, fridge, clothes iron. There is a cafetière.
Weekly cleaning and change of sheets and towels worked well.
There is no washing machine, but there is a launderette opposite and if you wash clothes by hand there is clothesline outside the terrace and also a rack for drying.
I was very happy in my choice.
