Mário was really friendly when we met him in Porto. He had some water problems with our arpartment so we could not sleep the first nigth in the arpartment we booked. But this was not a problem at all because he drove us with his car to another flat which was only 10 minutes away from the original flat. The other flat was really nice so we can say that he actually upgrated us. The next day he picked us up in the flat and drove us back to the original flat. We can say that everything was really clean and nice. If I come back to Porto I guess I would choose him another time.
