My boyfriend and I had a great experience at Joao's apartment. We did not meet him, but Sara who let us in was very friendly and helpful. We went to some restaurants she recommended and they were the best we found in Porto. The room was big and bright, and the whole apartment was very nice and gets tons of sunlight. There's a patio just outside the bedroom that's a great place to sit and eat breakfast. They also provided coffee, tea, muesli, and other basic kitchen supplies. The location is great too- walking distance to the water but also very near a metro station. We wished we could have stayed longer, and would love to come back!
