Visiting Buenos Aires- training?

Hello All-

I went on vacation last year to Istanbul and met someone on this site who arranged for me to train at his dojo and it was an amazing experience. So, I'm giving it a try again. I will be in Buenos Aires from November 17th - November 26th and would love to train while I am there. I'll be staying in San Telmo during the trip and can train any of the days that I am there except November 19th. Does anyone know of a dojo near San Telmo that is open to drop in aikidoists?

A bit about me: my rank is 4th kyu, I've been training for about 3 years, the style at my home dojo focuses a lot on long blends, I live and work in San Francisco, and I don't speak Spanish.

Any information or suggestions would be greatly appreciated.

Thanks,
Whitney
