Mario’s places had the best location for a self tour of the best spots in Porto! It’s only about 5 mins walk to the center and most tourist spots are just close to one another. The cleanliness of the place was perfect, couldn’t ask for more. Convenient self check in process with the keypad was a plus. Though shower might be a bit small if have a large built. Also if you carry big luggages like us, you had to carry it up to 3 flights of stairs as the room is on the 3rd floor, which is kind of hard but possible. Will definitely book at Mario’s place again! Thank you Mario!
