I've stayed in Buenos Aires several times, mostly in Palermo and this was my favorite apartment. I usually choose luxurious apartments, but this was the nicest to date. The view was incredible, I can't imagine many apartments in Buenos Aires having comparable panoramic views of the entire city.
It truly is a penthouse apartment, unlike many of the listings on Airbnb. You will have the top three floors of the building and although the rooms are not very large (hard to entertain many guests) the outdoor areas are large.
Overall I give my experience 5 stars and would HIGHLY recommend this property to anyone looking for an upscale apartment right in the center of Palermo.
