Joao is a very nice host who gave us many recommendations and advice for our trip! We didn't have any plan when we arrived Porto, so we followed his recommendations and had a wonderful experience in Porto! We arrived in the evening, he's even so nice to pick us up from airport! His house is very big and clean, with amazing river view!!! They have also prepared a bottle of Porto wine for us, which is literally nice and tasty! Location is wonderful that can reach lots of scenic spots by walking. It's a quiet corner hidden in the city centre, highly recommend!
