I had a longish stay (3 weeks) in this apartment and it was a great experience.
Pros: The apartment was very nice, really big and comfortable. Everything you might need to feel at home was provided. The building is great and location is excellent. Good office space, nice appliances.
Cons: I was surprised to see only one TV set in a 2-bed + living room. The one TV was not Smart so I would recommend bringing a Chromecast, Fire TV or similar to be able to use streaming platforms.
It was quite cold and windy in Buenos Aires during my stay and so I had to use the heaters. They would usually go out due to the wind, and they were hard to turn back on.
Daniel was really helpful. I had a minor issue with the wi-fi on the first day and he helped me fix it immediately. I also had an issue with the electronic door lock and Daniel was very responsive and helped me sort it out as fast as possible. Overall a good stay, I would probably book it again.
