The place of Luis is amazing, the room are very high and well arranged, for once in a rbnb the artwork hanging on the walls were trully good. The location is great to discover Porto and the flat has everything you need. The main street is a bit loud but the new windows in the bedroom are well soundproofed. Luis was very helpfull for the checkin and the checkout, the cleaning lady was also great and gave us some tips.
Only 2 things you should know: the entrance of the flat is on the junkies street. We told our portuguese friends about it and they all agreed, nothing happened to us but we made sure to come in and out quickly and to lock the door well after us. The second thing is that all the lights in the flat (except the bathroom ones) are terrible > cheap ikea eco bulbs - displaying a cold hospital like atmosphere while the few other lamps are working for 50% of them. Also two windows were broken and didnt close properly, but the weather was great so no problem.
