This is a wonderful apartment with room to place your belongings. For a month stay they have a good washer and a drying rack to dry most clothing in a day, at most two days. Water pressure is strong in the bathroom. TV channels are sufficient, and you have everything you need like a fridge, utensils and a large closet.
Neighborhood is the best, you're one street away from a street with all of the best restaurants in Porto and you're close to the Trindade metro station which serves 4 metro lines.
Would definitely recommend this place!
