Superb location in the heart of Palermo, close to supermarkets and anything else you may need. Apartment is fully equipped with amenities (it even included wine during my stay).
I recommend spending the first few hours going to the nearby supermarket and enjoy a table of Argentinian meats, cheeses and some wine while you relax in the hot tub in the second floor.
If you're still looking for tickets, I recommend you choose the Aeroparque (AEP) airport, it is about 20 minutes away from vs 1hr to Ezeiza (EZE)
Finally the host is very friendly and responsive. Soledad went above and beyond to ensure our stay was a pleasant one.
