I came for the carnival and was so lucky as to get a last minute booking with Gonzalo. He and his family were very nice and had freed rooms for the busy period (I was sleeping in the room that was normally his sister's), always home to be ready to let you in, and his mother cooked a fine breakfast. Fine and uneventful location in the middle of a residential neighborhood in the relatively safe "Zona Norte". No aircondition, but there's ample ventilation in the apartment so that was fine. A place where people also live, I wished I had been travelling with ear plugs because of the music and tv from the living room in the mornings, but overall a very fine experience that I would do again.
