This apartment suited our needs perfectly for our week-long (honeymoon!) stay in Buenos Aires. While it is small -- about the size of a standard hotel room -- it had everything we needed: comfortable bed, kitchenette (stove top for tea/coffee and mini-fridge), modern bathroom with good size shower, bureau and drawers for storage, small balcony overlooking some of the "hot spots" in Palermo, and - importantly - AC! The building had other amenities (a small gym, a rooftop pool) that we didn't take advantage of, but appreciated that they were there!
Also, we loved this location in the heart of Palermo. We ended up crossing town most days to get to the major "attractions" in BA (teatro colon, cementerio recoleta, La Boca, etc.) but were always glad to end our days with food and drink in Palermo, and then walk home. Highly recommend if you want a comfortable, clean landing spot for your time in BA!
