Honestly, I do not recommend this host at all, but let's start with the good points:
The location of the place is unmatched, Las Cañitas is an amazing neighbourhood with tons of cafes, restaurants, bars and parks nearby.
Andrea was very helpful with the check-in date and gave us the keys a day earlier and was very kind and welcoming.
Now, the place: It's a cozy apartment, almost identical to what it looks like in the photos. The previous review mentioning the safety hazard was not crazy. You actually have to be aware of the AC water disposal, something that was never mentioned until the check-in. The AC and the apartment itself were pretty old with tons of tiny little details that made the experience a bit unpleasant but bearable since we were there to sleep mostly. During our stay, we rarely used any of the kitchen appliances, primarily just the Nespresso coffee machine (which had new capsules ready to use, I must mention), yet the faucet had an issue our last day and there was water all over the place. We reported this as soon as we cleaned up the mess and Andrea was not hesitant to mention we were the ones that caused this damage.
We never expected this reaction from her based on the kindness she'd shown initially. However, she totally changed and forced us to stay so the plumber could check the damaged item (on our last day there) when we needed to do tons of things such as PCR tests to be able to get back home and even tried to charge us for the damaged (very old) faucet, including associated repair costs.
As I mentioned, the location is unmatched, for me, there is no better neighbourhood in Buenos Aires than this one, the place is ok, but if you plan to stay there, be aware of the A/C thingy, and that you might have a similar experience if any of the other incredibly old items in the apartment suffer damage while you're there, as the host will show who she really is and try to charge it even if you did no damage whatsoever.
We have always tried our best to be nice tenants, taking care of the home as if it were yours (even more). Yet, there are always people out there that all they care about is their own interests and are only nice when it's convenient for them. Such as shame.
