Mario is a great host! Very attentive and communicative, he was able easily accommodated check in and out times according to my flight schedule, and he promptly responded to any needs I had regarding accommodation. I also love the apartment, for the budget it had everything I needed. Could not have asked for a better location!! On the same block, it has plenty of cafés, groceries stores, restaurants, bakeries, bars, and hidden bars/clubs. It is also minutes away from many of Buenos Aires main tourist attractions.
