Maria's apartment is Retiro is just amazing. It is close to nice shops and restaurants, a mall (Galeria Pacifico) and public transportation (both buses and subway lines). If you are in Buenos Aires for tourism, you can walk to Puerto Madero, Retiro Station, or Casa Rosada without much effort. The apartment itself is a beauty, recently renewed, very spacious and bright. It is located in the back of the building facing a little patio, so it is both pleasant and quiet. The kitchen is well equipped, perfect for cooking breakfast or dinner. Maria and her family are kind and responsive, always willing to help and very flexible. They are perfect hosts. I highly recommend this apartment.
