This was our first visit to Argentina. We did not speak Spanish and we were traveling from the USA with our mobile data turned off. WIFI in the airport allowed me to contact Cesar about our early arrival. It was a very early hour but Cesar invited us to come to the apartment much before normal checkin time. Cesar speaks Spanish and spoke English with us. Our biggest concern was getting to the apartment from the Ezeiza airport. Though Cesar had told us of the various taxis and confirmed that UBER was also an option we purchased fare for ARBus per airport information booth guidance. They told us to get off the bus at the 2nd exit (Belgrano). Helpful bus riders used their phone to alert Cesar and he was there on the street in front of the building to welcome us to the apartment.
Cesar was very friendly and carefully pointed out how everything in the apartment worked and where we might go for groceries or currency exchange. Cesar was astute in knowing that some of his words were received by weiry travelers and made it a point to be friendly and helpful but then to allow us to rest.
The apartment had everything we needed for our stay and
was perfected located in the center of the Milonga (tango) events we attended which were listed on Hoy Milonga site. I found it impossible to be sure where to pick up the ARBus for our departure and instead found that UBER was the best choice. Fast and about $14 US dollars.
