Carla's place is extremely well situated. When I arrived in Porto at the airport I purchased a 20 euro metro ticket, figuring I could top it up as needed. I took the metro to Carla's place ...and didn't use my metro ticket again until 16 days later when I took it back to the airport - the location is that convenient. The apartment was great - nice kitchen, sitting area, separate bedroom and bath. I particularly appreciated the motion-activated lights in the outside hallway that would automatically turn on when I returned after dark. I would happily stay there again.
