We had a really bad experience with this woman who considered she could rent an appartment and make a plumber work in the morning for 3h at the same time. She announced a guy would come at 9 am just the night before. When i said it would not be possible because we were sleeping, that it would be ok only at 11 or 12am, she became hysterical, and even insulted me. She said she was the owner and was entitled to do the work, that anyway we were tourist and should be out visiting the city. So we had no choice. We got up at 8am although it was raining like hell in buenos aires and waited... the guy never came and she didn't keep us posted. "Kikki" is not a nice private individual renting her own appartement, she's a businesswoman (probably working for an agency) and not a professional nor honest one in my opinion.
She will say that i was not cooperative. I consider that when i rent an appartment i shouldn't be kicked out of it. Especially since she didn't apologize for organising this appointment and didn't ask nicely.
