I spent a week at this place, Paul wasn't there but Mari was an excellent host!
She speaks both English and Spanish, a very friendly and interesting person to talk to. She helped me settling down in Buenos Aires, thanks Mari!
The apartment is very well located, 5 minutes from the metro station Indipendencia and few blocks away from the heart of San Telmo.
Groceries, cafes, markets are just few minutes away.
My room was comfortable, a bit noisy as they're doing construction works next door but they'll finish soon.
It's the place to be in San Telmo - thank you Mari!
