Apartment has a very cozy terrace, we had breakfast every morning there (and it was the end of october!). Graca district is quiet, you will need ~20 mins of walk to get to the old center. The walls are either super thin or the acoustics of the house is so special that you hear the neighbors entering the doors and walking upstairs very well. If you come by car, better leave it at the Santa Apolonia parking lot (15 mins walk from apt), 8 euro per day. There's also a record store right on the Santa Apolonia embarkment. 😀
