Catarina's apartment is very comfortable and large. It is just like the description. A friend and I spent 5 nights there. The view from the balcony is wonderful. The area around the apartment has everything you need and is quiet. It's an easy walk into the tourist area straight down the street next to the building. And the metro is very close, easy to get to and from the airport. Catarina's friends meet me at check in and gave me lots of information on Porto and recommendations for restaurants. Her father met us at checkout and gave us a ride to the train station. Catarina and her father were both very responsive to questions. I would highly recommend a stay at Catarina's apartment.
