Elba's place was super clean and close to the Congreso (line A) subte stop. In general, she was a very welcoming hostess and was kind enough to accommodate my travel schedule and a late checkout. She even helped me with my heavy luggage on my way out. She was pleasant and kind in our interactions.
The Airbnb listing says a kitchen and heat are available. When I arrived, she gave me a tour and said I could use the kitchen for simple dishes. So I started to prepare squash and onions on the stove. As I was not accustomed to the appliances, the squash burned a little bit. Elba came into the kitchen and scolded me, saying guests only are allowed to boil things, not fry. So of course I apologized and stopped cooking immediately. She continued to berate me, saying it was so hard to clean the pan. Since I was uncomfortable, I wanted to leave the kitchen quickly so I started eating standing up and she said, "Relax! Go into the dining room." I scrubbed the pan until it looked new but she was hovering in the area the whole time. It's fine if a listing does not have a kitchen, but if the host doesn't want guests to use it, then it should not say so on the page. Also, the yellow room was cold since it's winter here. I wanted to use the heater that was in the bathroom but Elba removed it while I was out of the apartment. So the listing should not advertise that it has heating available if guests can't use the space heaters.
In general, it was a pleasant stay and Elba is very nice and welcoming. However, her rules are very particular, and I broke 2 of them accidentally and ended up in an uncomfortable situation.
