The house is beautiful, super clean, comfortable and very central. It is just 10 - 15 min walk to the old town or if you prefer just meters away from metro and bus stations.
Luisa is an exceptional person. She is like a sister or mother to you, she cares a lot about you, tries to make you as comfortable as she can. Her husband Jorge is a wonderful person also. He helped me a lot about not only Valencia but the other cities I would visit later.
I don't know Spanish and they don't know English much but we talked for hours understanding eachother and enjoying every moment.
There are a few local restaurants just in front of the house where you can eat good food.
If I visit Valencia again, I definitely know where to stay now.
