Ariel was an amazing host! He was very kind and answered my messages quite quickly!
Also, I had a problem with my flight due to Argentina's national strike so I arrived in the city later than I'd planned. He was very understanding about that and helped me out with it.
About the apartment: great facilities, very clean and beautiful! The location is amazing as well, with no difficulties you're able to go to the main touristic places of the city.
Thanks again!
