Ximena's place is very well located 30 seconds away from Matta (line 3) metro station. The room is located in a brand new apartment building and everything inside the house is brand new as well. The room has a single bed that's very comfortable and a small closet. The window in the room is gigantic (the size of the wall itself) and the views of the Andes over the city are superb since it's in a 13th floor. The kitchen is small but has enough utensils to cook simple meals.
Ximena is very nice and helpful. She also speaks several languages (even some Japanese!) so don't worry is you don't speak Spanish.
