I had a great stay at Cristina and Pedro's home.
The room was very clean and big, and there was a dedicated bathroom only for myself.
The flat is very well located, and it is easy to get everywhere in Valencia from it, either walking, or using public transport.
Much more importantly, Cristina and Pedro went above and beyond to make me feel welcome.
I have no hesitations in recommending them as your future hosts if you are going to spend some time in Valencia.
