Roberto is a great host. He is friendly and knowledgeable. The room he offers is outstanding for the price he charges. We were there during a cold period in January and the room's wall heater kept us toasty. There is a room air conditioner--so I assume that the room is cool during the warmer months. The location was less than a 10 min bicycle ride from the heart of the quarter. The homes around Roberto's are fine and there is a considerable amount of rebuilding and remodeling in the neighborhood. I recommend Roberto and his room without reservation.
