Hola, I work in non-profit here and there will be new group of volunteers coming this month from Japan (similar to a Peace Corp program). I have to help them look for an apartment in Buenos Aires. They need a 2 year lease with a monthly budget of US$400 (including expensas). The organization will be the guarantor (as they've always been without any problems). The volunteer that will be working with my organization is based in San Telmo area (Independencia y Chacabuco), so if there's any around there please send me note. Mil gracias!
