The apartment is exactly as the pictures show. The kitchen is well equipped and Alexandre provides enough towels, sheets and other household support. Communication with Alexandre was super easy and fast and he was flexible extending my stay. It's centrally located and you'll find everything in walking distance (well stocked supermarket is about 10 minutes walking distance). The apartment is very quiet when you close windows and I slept like a baby :)
Just one little deficit: The street is not the nicest/cleanest streets of Porto - but literally just 1 block away of a busy touristic street. I would nevertheless totally recommend this apartment - I stayed for 2 weeks!
