Mariana's place was clean and well organized. She was also good with her communication and responded promptly when I reached out to her with any issues. She facilitied us with a late check-in and was also gracious to extend our checkout time by 4 hours without any charges. When the bathroom sink got clogged and we reported it to her, Mariana helped sort it out within 24 hours.
With that said, her apartment has some challenges. Twice, the electricity circuit tripped up when we turned on the hot plates in the kitchen. One of the bathroom doors is frosted glass - clearly opaque but not enough privacy if you are visiting with a big family. Also, the apartment got filled with smoke coming from outside on one occasion - possible from a barbeque in the neighborhood. These can all be improved upon for guests with some attention to detail.
Separately, Mariana asked me to pay an additional amount for paint on the walls that she claimed got scratched during our stay. While I certainly do not recall it, we were a big party with kids, and it is possible that it happened inadvertently. I did pay the amount promptly.
