Ana Milena is an excellent host: she gave us her contacts and the address before we came to Buenos Aires. She also provided the immediate wifi access, so we could connect to wifi and contact her as soon as we got to the building. She also writes very well in Portuguese which was a great relief to us!
The apartment was super clean and the location is perfect: it takes 2 minutes to get to the Agüero metro station and it takes around 15 minutes to get to all the important places in Palermo and Recoleta. There were many things in the apartment to make the stay more comfortable: an iron, towels, even a toaster :)
At one point of our stay, we had an issue with canalisation but Ana Milena solved it within 2 hours after we contacted her. Choose the place, you won't regret!
