Mario is a good host! The place was clean and listing is accurate. The room is smaller than you think and would likely not fit two comfortably. There is also no air conditioning, and we visited in mid-July which was not a great idea. It was too hot to sleep for us. He does provide a fan which helps a bit but the heat was just too much. With that said, the location is fantastic, right in the middle of Porto, and we were given good recommendations as well.
