Maria Florencia (Flor) and Max were friendly and helpful. I came in late and couldn't get any currency exchanged and they kindly lent me AR$200 until I could go to the bank. Flor was so patient in letting me in at all hours of the night when I had problems with my keys! She provided a useful subte card for public transportation which was a big plus and her self-made neighborhood guide was handy. Flor and Max answered all questions I had about Buenos Aires and I spent a lovely week there. The icing on the cake was watching the Orquestra Victoria, a talented tango orchestra (Flor plays the violin) perform at the CafeVinilo my last night in Buenos Aires. Enchanting!
