There are a lot of great reviews on here from good experiences but I will say I have mixed feelings (both good and some disappointments) about the place in general.
First the disappointments:
1) The place is advertised as being 40 sq meters. However there is a good sized balcony that is
included in the total measurement which brings the actual living space size down to somewhere between 30 and 35 sq meters.
Although the place is nice and very new, I personally think it's too small for the very hefty 2000 USD/month price tag (including fees and taxes).
2) The location was in a safe neighborhood but undesirable for me specifically. I wanted to be walking distance from Palermo Hollywood Plaza or Palermo SOHO Plaza.
When I reached out to the owner I was told it was walking distance. The closest Palermo Plaza, which is Palermo Hollywood, was about 21 minutes walking.
I personally don't consider that walking distance and perhaps that should have been clarified in my initial conversation with her. The area is nice and had a few cafe's nearby but it definitely was not where I wanted to be. If you are a tourist looking for a quieter neighborhood that's not as trendy as Palermo Soho for example, then it's probably for you. If you are looking for something much more trendy like I was, It may not be sufficient for you. So it definitely depends on what you're looking for. In summary, before booking this place, ask the owner a lot of VERY specific questions if you are looking for something specific.
Now the good:
1) Although in some ways I felt mislead about the walking distance to Palermo Hollywood, the owner was very responsive and pleasant.
I am not accustomed to doors automatically locking when closing them and I locked myself out twice. She rallied and made sure someone let me in within 10 minutes both times.
I could have been locked out both times for hours with other property managers and owners but she was prompt in making sure I wasn't stranded outside the apartment.
I also needed extra towels and an iron and she was able to get them both to me right away. She also gave me a ride to the next place I booked in Buenos Aires which
says a lot of good things about her character. I have been all over the world and I know most hosts lack a positive character trait like that.
Also, the building staff (Omar) was outstanding and the cleaning person (who spoke English) was outstanding as well.
2) As mentioned by other people who stayed in this place, everything is brand new. So considering most places in Buenos Aires are not like this, it was a big plus.
