Mara is an amazing host. She is thoughtful and very helpful with anything you need, I can say for sure that she goes beyond any expectation, even though we do not speak the same language, she put all her efforts to make sure that I was having a great experience.
The place is very nice, the cleanness is astonishing. Very well located, close to literally anything you need, Coffe shops, Restaurants, Pizza places, drug stores, markets, You name it.
If you do not mind walking, you can easyly walk to some of Buenos Aires popular sightseeing but if you do, the public transport is very close and you have taxis driving around all the time.
I would recommend her and would return if the opportunity comes.
