Juan recommended a taxista, Daniel, to pick me up from the airport and take me directly to the apartment. Daniel was great, he waited even though my flight was delayed and helped me with all my bags. Upon arrival at the apartment Gabi, Juan's wife, was waiting with the keys. The apartment is centrally located in Palermo - right near Plaza Serrano which has many good restaurants and nightlife, the botanical garden and parks, etc. Everything was clean and in working order and check in/out time was flexible.
