Silvia is really reactive and well organized, she answered quickly to our message and give us very useful recommandation of restaurants in their handbook. Appartment fully-furnished and well located if you want to visit the center. The appartment smells a little bit when we just come back from outside because it is an old building, but after opening the windows and a few minutes inside, it desappears.
By the way, the appartment is still beautiful (as in the pictures) and recommand it for those who want to visit Valencia for a few days :)
