This is my second stay with Debora and Sergio (they have another unit next door). I can't say enough about how lovely they are...honest, genuinely helpful, gracious hosts. Sergio tended to me like I was a visiting political dignitary. Debora arranged for satisfaction of some special requests instantaneously. After after a visit when I fell a bit ill, they have become my defacto Buenos Aires family. The space is stylish and clean, quiet and spacious for 1 or 2 people. I chose it for the gym (which is well-appointed and almost nobody uses) and the location on the outskirts of Palermo (not super-close to the center, but walking distance to everything, and quiet). Several excellent restaurants/bars nearby. It's the only place I want to stay in Buenos Aires now.
