Mario is an experienced host. He had prepared everything throughout our stay - with a neat and tidy flat (modern, well decorated and looks even better than the photos!), travel guide etc. Even though we didnt get to meet before our check-in, he is so helpful and responsive in replying my enquiries. The location is perfect - just opposite to metro and it is so near the main street. We had a great time at the place!:)
Also, Mario's travel app is convenient during our stay in Porto! :)
