Luis is the best host I've ever met from airbnb. He sends you very useful information and tips everyday, we followed some of them and were very satisfied with them! Also, communication went always very quick per whatsapp. The apartment was very spacious for us two and had everything needed, plus balcony and bathtub! Location was just perfect, nice cafes and restaurants nearby but not noisy. Luis even provided us a bottle of wine, some fruits and bread, which was very kind. Overall, our stay at Luis' apartment made our trip in Porto much better.
