The place looks a lot better than the (current) pictures tell you. Our group was surprised how big the apartment was and how much light goes into the apartment. The pictures don't do justice how the apartment can look bright with the sunlight.
Location wise it was perfect. Close-by the city bikes (I recommend paying 13eur for a week of city biking) as there are multiple places close and distance to the sea it the same as going to the centre. Valencia is very flat, so it's easy to get around.
On our arrival there was some water and croissants waiting for us, which was really appreciated since we were all super thirsty.
