I didn't have the opportunity to meet Belen, as she had to attend some family issues. But her husband Avelino and their daughter are both very friendly. Avelino made sure I had everything I needed and the room and bathroom were clean and comfortable. Avelino also gave me some good tips to what to visit and where to eat. Their apartment is located within walking distance to the main touristic attractions, to the metro, and to shops. It is very quiet and has a beautiful view on the opposite park. One of the best location in Madrid I think.
