Stayed here with my family for 11 nights recently. The flat is great with everything you need for a longer stay. Very modern and clean with quality appliances throughout. Very comfortable mattresses!!Heating in all the rooms worked great (was important to us traveling with a 5 months old baby and coming from the tropics). Slight downside, there was no heating in the bathroom (with the bathtub) on the closed veranda, which would get quite cold, so impossible to bathe a baby. Again, only relevant if you have small kids that like the warmth 😀
Paula and Rafael were very friendly and responsive in their communications, even before check-in. The area worked for us because we had a car and it was easy to explore the areas around Lisbon. LX Factory is a 10 min walk or so with lots of restaurants. Lots of local cafes (pastelarias) nearby too.
To get into central Lisbon, we used taxis or took the bus a few times, which was fairly easy. Overall, great stay.
