The apartment of Helena Team is great located and extremely beautiful, really spacious, good bed and beautiful balcony. It is perfect for a couple!! We could not meet the hoster because the apartment is part of a rental company, and they send you different codes to open the front door and to open the box with the keys (it works as if it would be a hotel, basically). It was really close to the center and you can reach all the main points of Porto easily! Thanks!
