This was a great home away from home. We were in BA for a wedding and quick tour of Argentina. Ralf was very flexible and accomodated our late arrival so we didn't have to miss out on plans due to a cancelled flight. His associate Marcello was absolutely great and, despite us checking in after midnight on a weekday, he took his time going over the apartment features, giving us tips and making sure we were comfortable. They even had some bottled water and fresh fruit waiting for us which is a little touch that can go a long way for a weary traveler! The building is amazingly secure and in a very safe neighborhood with lots to see and do. We would absolutely stay here again!
