Outstanding apartment, we had a very pleasant stay! Maria was hostile and easy to communicate. Apartment was clean, nicely decorated and with great paintings, furniture and other cute touches. Kitchen was fully equipped with all necessities for cooking. There were branded shampoo and shower gel in bathroom. Maria also gave us quick guide about waking around Porto. Were to park cheaper, what places to visit, etc!
PS: there is a boat transfer to other bank of a bay close to apartment. you can catch up a classic Porto tram there to get right to the city center.
A big Continente supermarket is 15 min walk.
I highly recommend this apartment for your stay in Porto!
