Luis was a great host. He promptly answered every question that I asked throughout the whole visit and offered further helpful advice on the subject. He met me right on time to give me the key, quickly walked me through the apartment, pointing out the basic amenities and answering my inquiries. He was very friendly and made me feel right at home and comfortable from the very start and throughout the eight days that I stay there. He also helped me out with the money exchange. If/when I go back to Buenos Aires, I would hope that this place was available.
