We had a great stay in Porto! The location of the appartment is really good, only a couple of minutes from the Ocean. Nearby you can find really declicious resturants and cafes and very nice shops (especially for baby clothes :-). Praia the Luz and the Cafe at the beach was our favorite location.
The flat was equipped with everything you need: there we a couple of heaters which we used since it was a bit cold in the flat. The bathroom is newly renovated, but the rest is pretty old, humid and smells like old furniture. From the pictures I would have expected much newer flat and also a bit bigger than it actually is. The matraces were also pretty hard, not suitable for people who like it more soft and comfy.
We arrived at the middle of the night and thanks to the automatic check in it was not a problem at all to get into the appartment. On the very last day I called Carolina to ask for a later check out and it was possible, so the hosts are really friendly. What I missed a bit was a more personal contact, we often book via AirBNB and had already very nice experiences with hosts who gave us some insider information and reccomendations concerning where to go, visit, eat and so on.
I would definitely reccommend this neighborhood to stay in Porto!
