Everything worked out at the perfection: the property is located nearby a subway station and a very trendy cultural neighborhood (Barrio Italia) and the house itself corresponds exactly to the description.
Maria’s brother was waiting for me even though I arrived quite late (I advised her on the travel plans change) and he gave me a “tour” around the house and explained how everything works.
Maria’s house was equipped with all the basic items and she was so nice to leave even some non obvious items like a new toothbrush!
As an abstract, I recommends Maria’s house without hesitation!
