I made the reserve 3 hours before arriving with the train at 9pm and at 9:30pm I was inside the apartment and all was perfect, good service of giving keys! The apartment is next to the train station and the subway so you don't need to take taxi. You won't hear the trains or the cars, the windows are new. The apartment is new and it is very clean. In the next months I have to return to Valencia because of my job and if it's free I'll reserve this apartment again.
Opposite the apartment there is a Trattoria but everyday they have a different plate of typical Valencian paella and the menu costs only 9€, first and second plate, dessert and drink and it's all great. I had lunch the three days there very good.
I recommend a lot the apartment!
