We absolutely loved this apartment! It was easy to find from Porto airport - we jumped straight on to the metro and got off at Campo 24 Agosto. We were met by Carla's dad, who was very friendly and showed us around the apartment.
The location is amazing! We walked pretty much everywhere as its not far from the centre so it's an excellent location to see all of the sights. I read reviews before arriving about it being on a "seedy street" and about 2 brothels. I can honestly say that we didn't think this at all! I wasn't intimidated walking along the street and I didn't think it was seedy either.
The apartment was really nicely decorated! I loved this place and I would definitely return!
The only thing I would comment on is that the kettle probably needs replacing.
