Saras apartment is really chic and big with nice equipment.
We parked our car in the garage.
You can reach the center of Porto by bus within 30-40 minutes.
Sara herself was really nice, courteous and helpful.
The only negative things were that it was a little cold (but that wasn't a big problem) and the bathroom was a little moldy (but it was clean nonthless).
I recommend Saras place :)
