Carlos and Elisa are fantastic and very caring hosts. They came to pick me up from the airport and also do the drop-off on the day of departure. Their Recoleta apartment is huge, more than enough space for 2-3 people. It is in an older building, but very secured with doorman and the apartment unit is actually on the very top floor of the building. It is within walking distance to the main attraction sites, eg. Recoleta cemetery, Plaza de Mayo, Plaza San Martin etc and food and shopping options. Highly recommended for various reasons!
