I had a wonderful 3 nights staying at Joao's place. I was greeted by Simone and she walked me through recommendations of what to do in Porto & I had a great time talking to her! I only caught Joao briefly before my leave, but he was very friendly too. Downtown is an easy 15-min walk away and the city is beautiful. I'd definitely love to stay here again if I get to visit Porto again in the future!!
