I spent a few days with my girlfriend in Filipas apartment and we had a great time there. It is a lovely place with a very big balcony where we enjoyed a nice breakfast every morning. You have everything you need at the apartment and it looks even better in real life than at the photos :)
It is good located, with a bakery 1min, a supermarket 10min and the metro just 5min away :))
Filipa and her father gave us many many good advices what to do and where to go in Lisbon. We even got a privat transfer to the airport :D
So, believe me, it is really the best place to stay at ;)
