The two best aspects of our experience renting this apartment are its location, and the very friendly and helpfull rapport with its owner. It is located in a top Buenos Aires neighborhood, though not jet set or aristocratic. There are cafés and restaurants just around the corner. It is within walking distance to the nice Palermo forest-gardens, the botanical garden, the subway or "subte" stop in Plaza Italia is close, as is of course the busy Santa Fe Avenue and Old Palermo, now called Soho and Hollywood. You can catch a bus or a taxi right around the corner. It is very easy to give taxi drivers and friends the directions to get there, you just have to say it's close to the U.S. Embassy, and everybody knows.
The owner is very friendly, though absolutely not intrusive. She will respond right away if you call or email her for any information or whatever help you may need.
The porters in the building are also very serviceable and friendly.
We will return there.
