Very nice apartment and stay in Porto. The apartment was clean and the communication was easy and quick. Nothing over the top but no complaints. The location is about 20 minutes from the main city center, which I liked because I didn't feel like I was in the middle of a tourist area, but could still walk there in 15 minutes. It's also quiet and close to a great locals market, so if you just want to grab a bite and have a glass of wine without a big fuss there is plenty local spots near by. I didn't meet Antonio, but the woman who let me in was very nice and responsive via text. I would stay there again next time I'm in Porto.
