San Telmo area was recommended by a friend who spends considerable time there. It's very active with plenty to do within walking distance. The S.T. Market has both antiques and excellent food booths. Directly across the street is a nice bakery (closed Mon). Within 1/2 block, you can quickly/easily hail a cab. Except for to/from airport, I walked or rode bicycle (rental w/in 2 blocks) everywhere. Laundry service & grocery - 1 block. S.T. is a somewhat "bohemian" neighborhood, with lots of street activity and people of all ages/types, local & not. I felt safe there (though I was not on the street late night) and really enjoyed the energy/vibe. The unit is in a converted building, clean, lovely and well-equipped. Bed was comfortable (though a little hard for my taste). One "con" comment: It needs new bed pillows. Host was highly responsive (practically immediately) and communicated everything I needed to know. Price was good for the accommodation.
