This was a great find for me. It put me near the center of San Telmo without all the noise.Just around the corner are at least five good restaurants and an ice cream parlor. One of the better steakhouses in BA is two blocks away on Defensa.
One of the jewels on av. Casera is a bar/restaurant/museum called Napoles.It is filled with antiques including old race cars and motorcycles. A romantic dinner can be had at one of the tables lighted by a candelabra.
