Mara, Juan's partner, did all of the communication before and during our visit and was very helpful. We especially appreciated her arranging our taxi between the airport and the apartment - the driver was great! The location in Recoleta is superb and walking distance from the cemetery and many nice shops and cafes, as well as subway and bus stops. If you change USD to pesos with Mara, be sure to bring larger bills as you will get a more favorable exchange rate. We enjoyed our stay!
