This is a nice, clean room in a great location. If you expect to be out on the town for most of your time in Porto, this is a great choice and a great value. The metro is close, as are many shops and restaurants. Manteigaria, which I think makes the best pastel de nata, is only minutes away. As with any apartment in a big city central location, there is noise from the street and some nearby construction. However, the windows block almost all the noise, and the room A/C is good and quiet. There are a few downsides, the room is small, and can be tight to move around in, especially if you have a few suitcases. There is a shared dining room/kitchen, which does offer some additional space though. Also, there is no elevator, so be prepared to climb some stairs.
