I travel to Buenos Aires frequently, and would not hesitate to book this apartment again. It is well-furnished and comfortable. It is ideally located, close to public transport (subway) and close to restaurants and shopping. It is a safe neighborhood (typical of a large city).
Some things to note; any criticisms are minor and simple FYI. The door staff are fantastic and helpful. Like most anyplace in Palermo, it can be a bit loud at times, augmented by construction of two new buildings nearby. The public gathering/pool area is essentially just off the balcony and can be a bit active, especially during holiday times (Jan). There were some household basics (cooking/cutlery, oil, tea, etc) and plenty of soap and paper products, which is appreciated. Clean and comfortable. Closet a little wonky, as the panels are difficult on the tracks and always semi-block some of the closet compartments. Has a coded safe for money/cards/jewelry/passport. Host very communicative and supportive.
