Diouldé was a fantastic host: not only did he care for all of our needs as guests, gave us a warm welcome and was always available (phone/mail/or in person), but also he is a very helpful and funny host which makes you feel comfortable immediately. We laughed a lot and were happy to speak some french abroad :)
The place is located in a very artistic neighborhood, close to the city centre and in walkable distane of a metro station going straight to the airport. The room itself was spacious, clean, comfortable and had a view over Porto.
We would definitely recommend Diouldés place!
