We really liked the flat. It is spacious, light, clean, airy and comfortable. Both the living room and bedroom are served by very silent air conditioners (though it was a hot weak, the flat is so fresh that we only used the air conditioners a couple of times, for few hours), the kitchen is big, beautiful and comfortable. As for the flat, the only negative remark we would point is that the kitchen is not well equipped with pans and cooking appliances. Their was only one midsize casserole pan, and even to fry an egg we had to improvise. In fact, it did not bother us because we were not cooking at the flat, but it is something to take into consideration if you are planning to cook.
Our experience with Eugenia and her mother was very very good, and I am sure she would have provided us with the necessary appliance had we requested.
We had book her flat in Recoleta, which is also a nice and big flat, well located. But the air conditioner of the living room was not operational, and it was impossible to stay there, because it was a very hot week and the flat is in the top floor. She was sorry and very helpful, she mentioned the flat in Las Cañitas, a neighborhood we had never heard of, but we decided to go for one night so we could look for alternative accommodation. But we liked it so much that we decided to stay the whole week, and we would stay there again. Las Cañitas is not far from the most touristic areas, and offers the advantage to the in a nice residential area, with all services availabe, very near the booming Palermo area and a lot of small restaurants, cafes, bars, bakeries etc. I recommend it.
