Michael is super nice and helpful. I got into Buenos Aires early in the morning from an overnight bus, and he gave me specific directions on which buses would take me to the apartment. After I settled in, he showed me around the neighborhood, and even drew me maps for other places I might be interested in visiting. He also lent me a subway card, and some pesos when I ran out before having the chance to exchange more money. The location of the apartment is convenient and very safe as well, so I'd definitely recommend staying here.
