My wife and I just finished a three week vacation in South America, including nine days in Buenos Aires, all of which was spent at Soledad's wonderful apartment. The apartment itself, and the help and support we received from Soledad was in a word 'perfect'.
The apartment had all the amenities needed, and was spacious and immaculate. We made great use of the balcony and of course the roof top terrace with the jacuzzi (which we used on three occasions!!).
The apartment is in a great location, near plenty of great restaurants, etc.
Soledad was the perfect host - she (and her husband and two wonderful children) met us on our arrival and provided a great overview and all the necessary details. She was always very prompt in replying to any of our e mail questions, and arranged return transportation for us to the airport.
If we are ever back in Buenos Aires (which we hope to be) we will certainly want to stay here again, and we would highly recommend this apartment for anyone spending any time in Buenos Aires. It was truly great!
