I spent 33 days at Maria's house and it was very good. The apartment is spacious and they advertise another 3 bedrooms here on Airbnb, which is great for solo travelers like me to meet other people.
I work from home and managed to maintain my responsibilities without major problems.
The apartment is close to a metro station, several bus lines and the Palermo neighborhood.
Maria and Enrique gave many tips on tours in Buenos Aires as well as details of Argentine history and culture. And Norma (who takes care of cleaning) is a sweetheart too.
When I return to Buenos Aires, I already know where I can feel at home even away from home!
