If you're reading this review, do yourself a favor and go ahead and book this apartment immediately. Here's why -
The apartment:
Situated downtown, you are within walking distance of many popular attractions (e.g., Teatro Colón) and a quick underground trip from dining and nightlife in Palermo. However, the apartment itself is so beautifully decorated you may not even feel compelled to leave the apartment - as my travel companions and I did after a day full of sight-seeing. As a professional interior designer, Christina has truly created an oasis and the apartment is equipped with many accoutrements you wouldn't be accustomed to finding in a hotel (or even many other AirBnb's). We truly felt at home.
The hosts :
Even if the residence was a shack under a bridge by the rio de la plata, I would STILL stay at Eduardo's place because of how fantastic he and his family were as hosts. Prior to our stay, Eduardo helped us to arrange tickets for a local football game. After we were greeted at the door (with a beautiful, bottle of champagne no less!), Christina/Eduardo/Francisco remained in constant contact with us - providing recommendations for dining/entertainment/nightlife.
I will absolutely be staying at this residence on my next trip to Argentina.
