Cesar was a great host. He is a very warm and helpful person. He even arranged for a taxi to pick me up and to take me back to the airport. In terms of value for money, the apartment is a great place to stay at. It is centrally located ( near the Congreso [the Argentine Parliament]) and a 10-15 minute walk from the Obelisk, which is one of the city's most famous landmarks. It is close to the subway station and to many bus stops, so that it is easy to get around and to explore the city. There are many cafes, restaurants and shops nearby. I fully recommend Cesar and his apartment without any hesitations!
