Very nice apartment!
I stayed there with my brother for about two weeks and we really felt like at home.
Very modern and well equipped, as well as a super nice terrace!
The sun does not reach the terrace in winter so keep that in mind. In hot summer times this is definitely an advantage as it probably won't get that hot.
The garbage trucks come to empty the trash at night which sometimes is a bit loud. But I guess this is the situation everywhere in Lisbon and as the apartment has nice and thick windows it is not too noisy.
Overall a very nice stay!
