We traveled to Buenos Aires with our 4-months old daughter and we spent lovely time in Jimena's cozy and spotless apartment. There is nothing we can reproach. The place looks just like on the pictures, perhaps even better.
The location could not be better - it is situated in a very lively Palermo neighbourhood, just 50m away from the Plaza Italia which is Palermo's main transport hub with metro and bus stops going to all major places in Buenos Aires. However, the apartment is fairly quiet. Basically anything you might need during your stay (bakery, laundry, supermarkets, drug store, pharmacy, post office) is within a block or so.
Jimena is a perfect host. She was very attentive and answered all our queries within couple of minutes. We had several requests and she didn't have a problem with any of them - she found a baby crib and a pram for us which made our stay much more easier, she was always nice and available when we needed her and did not seem to be bothered at all.
As far as the equipment of the apartment is concerned, it has everything you may need. The kitchen has all necessary utensils, the internet is fast and the bed very comfortable. One can see that she put a lot of attention to make the place feel like home - the furniture and all the decorations are very well-thought.
We really truly enjoyed our stay there and thank Jimena for her friendliness and help she gave us.
