If you are staying in Valencia for more than a week, then I highly recommend splitting your stay in two like we did and stay 1/2 in Cabanyal in this condo and then 1/2 in the old town/rusaffa area. This condo is about 10-15 walk from the beautiful beach but you will have to take metro or taxi if you want to go to the city center.
We enjoyed our stay with 4 adults and 1 kid. Everyone had separate private space and open living room/kitchen were perfect for entertaining. The kitchen was well equipped and had a clothes washing machine.
Overall, we had a very comfortable stay and went to the beach almost every day!
