We came 2 years ago and came back this year. It was as usual, clean and functionnal.
The little garden is nice when you want to eat outside. If you have a baby there is everything that you need. If you have a problem ask Joana. The flat is around 15 mn away from the airport. You can use uber to reach the Center of Lisbon it costs 5euros for 2 people.
There is a supermarket 500m away (pingo doce).
Enjoy!
