I had a great stay at this place despite the pretty bad weather in Porto. The room was good, with a nice desk, a comfortable bed, good wifi, and a view towards a small green garden area. And even with heating as it was quite cold at night.
The guys that live here were very friendly and we had a few nice chats in Portuguese. For the most part, it was also very quiet - both inside the apartment and outside. And I cooked every evening and always had the kitchen for myself.
The location is good: a less than 10 minute walk to the Estadio do Dragao metro station, which takes you to the city centre in just a few stops and also has a direct metro to the airport. The next station (Porto Campanha) is where the urban trains (comboios urbanos) to Braga and Guimaraes stop; and there's a large bus station there as well. Finally, there's a large Mercadona supermarket at less than 5 minutes walk from the apartment. All in all a very convenient location
