We loved Marie's apartment in Palermo Hollywood as our base for a little over two weeks. A very spacious, modern apartment in a very nice building. The location was great - lots of restaurants and cafes at the foot of the building and just a short walk from the main strip of PH restaurants near Fitzroy/Humboldt.
We liked the added safety of having a doorman, made use of the gym, and loved having the rooftop pool on warm days. The private balcony outside the apartment was great to have to relax outside, or you could retreat inside to the air-conditioned interior.
The whole apartment is very comfortable - a great living room and dining room area with its own bathroom, as well as well appointed bedrooms as well. We have found in our Argentina travels that many rental places are at least a little banged up, and there are a few rough edges here and there. That said, none of this detracted from our stay and we found this to be a very high end spot to call home.
Finally, Marie was very communicative and had people to make check-in and check-out very easy.
This apartment was everything you could want in BA, and we would definitely stay here again. Highly recommended.
