I enjoyed staying in this apartment, and Marcos is an exceptional host. It is conveniently located in Palermo with a small grocery store across the street (which thankfully accepts Visa since I arrived without Argentine pesos and had to try four ATMs before finding one with cash the next day). There are also many great cafes nearby. Palermo metro station is a 12 minute walk. There was a lot of noise from traffic and construction, but that has been the case everywhere I have stayed in South America. I would highly recommend staying here.
