The last time that I was in Buenos Aires, an acquaintance of mine visited a couple of Houses of Boys as they were called. One of the houses was located at UribuRu 1059, Apt. 3P; the phone numbers cited were 4825-4292 or 4825-8560; the other location was at Arenales 2029. Their telephone number is 4821-8643 or 4829-2781. ...don't know if either or both are still in existence. If you're a future visitor to the city of portenos, and interested, please inquire and post back here for us. Again, the email that my friend sent to me has a five year date, but perhaps one or more or new ones have come about since that time. Future visitors please inquire and post when you return!
