Lovely apartment in El Carmen in the historic city center, next to the Turia river bed, with all facilities you need. We arrived late due to our flight and even then Jesus was welcoming and hospitable.
I wouldn't recommend the apartment for four guests if you are 'light' sleepers. One of the beds is under the window on the front side and it can be quite noisy.
In the end, a great place in Valencia and I would recommend everybody to rent a bike and explore the city.
