If your plan is to relax on the beach, then this place is the right one for you. A bit far away from the more crowded area around the port, but still reachable with a fine walk along the beach. The centre is pretty far, but still reachable by bus.
We have definitely appreciated the check-in, extremely flexible (we arrived pretty late in the evening!) and the apartment, absolutely lovely. We did enjoy the place a lot and if we come back to Valencia we will definitely try to book this place again!
