Mariana and her daughter, Katrin, were incredibly accommodating. They were understanding and pleasant when a flight delay pushed my arrival late into the evening (past midnight) and allowed me to store luggage on the day of my departure.
The apartment is in a nice area of Recoletta - near several restaurants and about 10 minutes walking to the subway. The small studio apartment was clean and had the basic necessities. Wifi signal was strong and consistent. A very good value in downtown BA!
