I had only a few days to see Buenos Aires, and Maria was a great help in making me spend my time without wasting a minute!
She had maps and tips and even a bus-card ready for me.
The room is lovely and spacious, the roof terrace is vast, the neigbourhood is perfectly OK, and public transport is near. Just as shops, groceries etc.
There are several rooms for guests, and in the kitchen ( also in the fridge) Maria gives everyone their own basket to keep their things in. Very well organised!
I wouldn't hesitate one second in staying at Maria's the next time too!
