We stayed in the apartment for one week. The apartment is located opposite to Casa da Musica. Although just beside the main road, the rooms are quiet as the windows have two layers of glasses. (Can hear the a bit of sound, but the noise level really manageable) The apartment is newly furnished with full amenities. Bed is comfortable. Vodafone shop is just downstairs. The nearest supermarket is 2-3 min away. Train station maybe 5min walking distance. (3 to 4 stops to the historic places in Porto.) Direct bus to the beach. Quite a few good restaurants around. Not to mention, the host communicate promptly and give very useful tips. Highly recommend, particularly if you plan for longer stay in Porto.
