I haven't met Sagrario during my short stay, but I kept in contact with her and she always always available to help. I met her friend Belen at the airport at my arrive. She is really kind and gave me the keys of the apartment.
The room is big, more than enough for a person and probably good for a couple. It has a nice balcony: it hasn't a breath-taking view but is excellent to relax a bit after a day around Valencia. It's position is fantastic: it's in the real center of the city, less than a minute walk from both Plaza de la Reina and Plaza Virgen but in a quite road. At night the room was a bit hot but there's a fan in the room that granted me comfortable sleeps. The bathroom was good but it hasn't a window, so after a shower might get hot. The kitchen has enough space, even though if I haven't used it a lot.
I recommend this room.
