I initially rented Barbara's apartment for one month, then extended it to two months, and then finally, to four months. It was that wonderful! The apartment is located in the most beautiful area of Retiro, across from the Plaza San Martín. There is a pharmacy on the corner, a fruit stand half a block away on Santa Fe, and two grocery stores and a subway station (San Martin) on the block. There is also a bus stop half a block away at the corner of Santa Fe and Esmeralda where busses 152 and 108 among others will take you directly to Recoleta and Palermo in one direction and San Telmo in the other. So it's very easy to get around to all the major tourist spots from here. For longer stays you should know there is a washer and dryer in the basement of the building, the latter is a rarity in Buenos Aires. In summary, a great place to stay.
