Filipas place was really nice for us to stay for 4 days. Its location is perfect to explore the city by foot or otherwise a tram station isn't far away. Rute, Filipas friend, welcomed us warmly and gave us a map with all the important sights. The flat was in good state except of some small issues (smell from kitchen and bathroom and the neighborhood was a bit noisy like to expect in a house with some apartments).
All in all we can recommend the apartment :)
