I stayed at Jacqueline's apartment with my friends and it was quite cozy and homely. It is near a Supermarket which sells essentials cheaper than in central (more tourist centered) Lisbon, that is always a good plus. The location of the apartment is also near a train station which also came in handy.
If anyone wants to rent this apartment in the future, just know that you have to walk around a bit to find some places of interest or you need to travel by trains or metros.
All in all, I would recommend this place to travelers who wish to stay in Lisbon.
