João was an excellent host. I managed to break one of the blinds and he was very prompt in getting that repaired, for which I was grateful.
The space is immaculate and located just far enough from the main drag that there is minimal noise, but close enough that everything (and I mean everything) is within walking distance. Provided you don't mind hills of course.
Would 100% recommend this place, and would stay here again. Sad I did not book a longer stay in Porto.
