I enjoyed my stay at John's place. The location is... great in that it is walkable to everything you would want (restaurants, coffee shops, etc.). The one annoying thing was that it's next to a loud traffic area which has cars, trucks, and busses honking and passing by all night. I had to get earplugs just to be able to sleep.
The internet is very fast, which was good for my work, and I thought the wine and the champaign included was a nice touch. But besides that, it seemed like a pretty basic place for the price. The basic necessities like toilet papers weren't included so I had to purchase them separately, which was a little annoying. The heater also wasn't working either, and since I was in Buenos aires when the winter was just starting off, it got pretty cold in some evenings.
Finally, I thought that the laundry and dryer was included in the unit. This was one of the main reasons I wanted to stay in this airbnb, since I find going to a laundromat inconvenient. But it was a shared laundry unit at the top of the building, which I accepted for what it was, but the dryer was broken anyways, so I had to end up going to the laundromat a few times per week (I didn't bring much clothes for the trip).
The hosts were great and kind people, and the convenient location made my stay at Buenos Aires enjoyable, but I probably wouldn't stay at this specific airbnb again due to the noise and the laundry issue.
