A group of 3 of us stayed at João and Ana's apartment and we had a fantastic time. The location of the apartment is perfect, everything in the center of Porto was within walking distance and there was a small supermarket less than 5 minutes walk which was very handy. Ana's mother Maria checked us in and gave us a very warm welcome and told us about the best spots to visit in Porto. João was also very quick to respond to any questions. The apartment itself was spotless and comfortable. The only thing I'd say is if you are a light sleeper you can hear the surrounding noise from outside but after midnight it quietens down, but all the benefits of the apartment outweighed that! Wouldn't hesitate to book again!
