The apartment is spacious and confortable, with great natural light and in a silent and well connected area of porto.
Is well equipped and clean.
We stayed with our 2year old son and the extra space in the living room was amazing for him to play with his toys.
The only downside, if you have too much luggage (or a stroller+child) is that it is in a 3rd floor without elevator.
Also, it is in a elevated part of porto, so walking to Downtown is great, close and easy, but coming back implies an effort. Luckily, the metro station Marques is near and the path is flat, so we used it to get back to the apartment from the river side.
Mafalda was helpful and received us at our arrival, even when we weren't sure when we would arrive exactly. And she saved the day when allowed us to stay a little longer to catch our late afternoon flight. Thanks Mafalda!
