Carlos's place is just great! The room is exactly like it looks on the pictures. Spacious, clean, tidy and neat! Suitable for a person or two people The area of the flat is very close to amenities, restaurants, landmarks etc... So you don't need to take the metro. You can walk everywhere. As for Carlos, he one of the best hosts I have ever encountered on this website. He is very talkative, approachable and friendly anytime during the day. He picked me up from the train station and gently replied all my questions about Porto and Portugal. He even helped me with my Portuguese. Highly recommended!
