The apartment has a perfect location and it contains everything that you will need for your stay. It has a numberlock system, which is very nice because you wont be worried to lose your keys. Avoid using the oven, because the warmth spreads into the room and makes the room really hot, making it feel like a sauna.
It's a very nice apartment and i would recommend staying here when going to Valencia. You do need to rent bikes, but you can park them at the appartment, so you can rent them for a few days.
