The apartment was clean and it looked just like the pictures: not too big, but it has everything you need. It is located in the city center, so you can walk to (almost) all highlights of Porto (but be aware: the city has some steep streets, so if you want to go somewhere further away, you can easily take a bus or the metro; both very cheap). Helena was very kind, showed us everything in the apartment and gave us tips on what to visit and where to eat (and drink). In Porto, go and visit a Port house across the river and if the weather is nice you can even go to the beach, there are some nice surf spots there. And don't forget to try Porto Tonico!
