Catarina was a great, helpful host, who picked us up at the airport even though we arrived late in the evening. She welcomed us with a bottle of wine and some refreshments which was really sweet of her. The apartment's greatest attribute is it's location, since it's two minutes walk from two big metro stations. The bathroom is small which was somewhat clumsy for us since we all are really tall, but still, the apartment served us very well on our trip and had a very authentic feeling to it.
P.S. The view from master bedroom is stunning!
