Manuel and Caroline's apartment is very modern and clean and has everything you need for a comofortable visit in Buenos Aires. Checkin is easy with very detailed instructions and a lock box at the entrance to the building. It is located in one of the nicest neighborhoods in the city, with plenty of great restaurants, a Jumbo supermarket, and a Subte (subway) station within walking distance. Manuel provides a Subte card. You just need to keep a balance on it. I highly recommend the Subte for getting around the cty.
Manual is very friendly and will make sure you have no problems with the apartment. Muchas Gracias Manuel!
