Mario's place was great to live in while exploring Porto for a couple of days. The location is perfect and so was the communication with Mario. Some minor things stood out as far the listed amenities (eg. the lack of hair dryer); the walls inside were visibly dirty too, what took a bit away from the overall impression about the place's cleanness. Overall, the listing is worth the money but I believe that with a few tweaks it could have easily became a much charming place to stay at.
