We stayed here for 2 and a half weeks. Maria’s apartment is in the perfect location for exploring Porto and for a longer stay - close enough walking distance to the old town, riverfront, etc. but not directly in it. Great restaurants right around the corner. We rented bikes and it was a short, beautiful ride along the river to many great beaches. I had to work remotely there for half the time and the internet was very fast (long zoom calls with video on and many browser tabs open). The dishwasher broke while we were there and they fixed it seamlessly with a new one in less than a day - very responsive, helpful hosts. Excellent soundproofing on the windows, so it was very quiet sleeping at night. 10/10 would recommend!
