The apartment is really nice and clean as in the picture. Alex and Carolina were really friendly and helpful, the apartment is centrally located, in a few minutes you arrive to the metro, bus or tram. The area is really quiet, and there are several restaurants and bars within walking distance, a very beautiful one is the Noobai Café site in miradouro of Santa Catarina where you have a wonderful view of the city till the bridge "XXV de Abril".
PS: ask Alex to tell you where you will find the Park cafe, you will be pleasantly surprised.
We stayed there for 2 weeks, and obviously we want to recommend it to anyone.
Obrigado guys!
