Jorge & Rafa's apartment it's ok.
The flat is right behind the central market and you can easily reach the city center in a minute walk. Buses and metro stops are basically everywhere.
I think they should do some improvement since the position of the apartment is very great! However the apartment's furniture is old and it should be clean more often, especially the common spaces and the bathrooms.
The room is actually as you can see in the pictures, the bed is pretty comfy.
I think for the price it is a good deal. Great for couples and for a weekend in Valencia.
