Luisa and Jorge are excellent hosts. As soon as we arrived they both greeted me and my fiancé and made us feel very comfortable. Jorge provided us with a map of Valencia and took the time to advise of the places to visit in the city and answered all of our inquires regarding Valencia.
The room with ensuite bathroom was lovely and the area the apartment was located was full of cafes and restaurants. The old city is within a 10 minute walk and the metro is 5 minutes.
I recommend staying at Luisa and Jorge's place if you are ever in Valencia.
