We arrived in the evening and were welcomed and shown the apartment by Pedro who was extremely kind and gracious. He very kindly gave us tips on where to eat, sights to see, and a bit of a sense of which were Porto's touristy bits and less touristy bits.
The apartment was as seen in the photos, clean, new, with all necessary amenities. It was very nice having 2 bathrooms to share between the 4 of us.
The location was very convenient - for getting to the metro as well as for exploring Porto by foot.
Would recommend this place without reservation.
