The apartment is great, very well located, clean and has all the amenities for your stay. It is spacious and can host 4 people easily.
Carloina, the host, is very pleasant and helpful, we haven’t met but we communicated several times over the phone.
One note to consider though, it can get very noise on the weekends due to the bar downstairs, you will only notice it if you are sleeping in the sofa bed in the living room.
Other than that, this place is highly recommended for your stay in Porto.
