Communication with Natalia was super good. We did not have any issues at all at her place. The location is quite convenient because many metro stations are around and the main touristic points are within a walking distance. The neighborhood has multiple variety of food offer and prices are not those for tourists. The neighborhood feels more like a real space in Madrid than a tourist-to construction. I loved this feeling.
The apartment can easily host more than 4 people and sofa is super comfortable ;)
