This apartment is just perfect. It looks the same as on the pictures. The flat is quite spacious, very comfortable and extremely clean. Anahi is just a perfect host. She waited for me in front of the building, then showed me the apartment and recommended me what to visit in Buenos Aires. She also organized the transportation from the apartment to the airport on the day of my departure.
Next time when I come to Buenos Aires, I already know where I will be staying :) Thank you for everything Anahi.
