I stayed at Beatriz's apartment for five days and it was a wonderful experience. The place was truly as good as shown in the photos when I visited, very well equipped, spacious and impeccably clean.
Within a five-minute walking distance from the apartment one can find a shopping centre with a Walmart, a metro station (Barranca del Muerto) as restaurants both fancy and budget.
Beatriz was a great host, always very kind and willing to provide assistance. Communication with her was very fluid from the time of booking. She lives in the same building and thus is always available if one needs help with anything.
I highly recommend this place.
