Marie was a very responsive host. Even though I did not meet her in person, her associate (Claudia) was very nice. The apartment is located in one of the greatest neighborhoods of Buenos Aires, full of cool shops and amazing restaurants. The building is quite impressive, with a great swimming pool to cool off your days.
The apartment was quite beautiful and comfortable with a few minor maintenance issues should be taken care by the owner, but that's nothing that would take away from the experience. I had a positive experience staying in this apartment and would have no problem coming back.
