If you are working remotely or will need wifi DO NOT book this one!
I mentioned to Ari, before booking, that I work online and that I need just a 10 mbps (relatively low speed). Ari confirmed and insisted on that he provides more than 25mbps in the apartment... Wifi in the apartment is extremely low, for not saying nearly inexistent, as the speed is lower than half of 1 mbps. When I mentioned that, Ari first was very agressive and said "no tienes suerte amigo" meaning I am not lucky and that's all.. after insisting he came and he noticed himself the problem to which he just said that the wifi is shitty in all buenos aeres which is the biggest lie ever (I've been in many airbnbs in the city and the internet connection is absolutely excellent in this big modern and beautiful city ^^).
He was very agressive and threatening while I was the victim as I could not attend any of my meetings and lost a client because of the inexistent wifi the first day then spent all my stay working from coffee shops as no internet in the apartment. Note that the wifi modem IS NOT inside the apartment.. he is using the wifi from some other apartment in the building. I asked to be reimbursed for 1 night out of the 3 I paid for and he got super agressive and refused. I am dealing with the airbnb platform for this matter.
All in all, do not go there if you think you would use the wifi. Also Ari is not that kind of nice and sweet host everyone wants. He needs to calm down and be respectful with ppl and recognize his mistakes.
Beside that, I can add neutrally that the apartment was clean and the view from the balcony is nice.
Now you know!
