Mario's place is even better than the photos indicate. It is well-located -- quiet but close to restaurants and bars, and in a safe area that is close to transportation and walking distance from a lot of attractions. The large Testaccio market is right next door, and had great street food and produce. The 3rd floor apartment has been recently renovated, and is very comfortably outfitted, and there is an elevator to get luggage up there. The entire place was clean, and the bathroom in particular was lovely -- it has a monsoon shower, which made bathing a real pleasure! The kitchen is well-equipped and has both microwave and regular oven. For those staying longer -- there is no washing machine, but several laundromats very close by. There is a sofa-bed in the large bedroom that was super-comfortable, and the other beds are too. Plenty of closet space for longer stays as well. Luca was very responsive, and clear with directions/instructions. This has been a great find -- I will be trying to stay here on other visits to Rome.
