My stay at Maria's house was estupendo! Her house is very big, bright and tidy, and is located in a very nice, calm and secure area - el porvenir (next to the park Maria Luisa, 5 min to Plaza de España, 15 min to the town center/cathedral by foot). I immediately felt comfortable there. Maria herself is a very friendly, kind and outgoing person, she takes care of her guests and is always on the spot when her help is needed. For an extra charge she also washes the clothes of her guests or cooks, which was really worth it, as she is a great cook.
All in all I totally loved staying there, and therefore I highly recommend it!!
