We rented the apartment on the second floor for 9 nights. Location is splendid. We know Valencia well and the apartment is perfectly located for beach and bars and restaurants of the vibrant Cabanal. The terrace is fantastic with view on the beach. The terrace is shared with the flat on the first floor so if you are not the same family or friends renting the 2 flats it is good to let each other know and you will not have any issue. The description though could be more clear that terrace is shared.
Just a couple of points for improvement. Toaster was not working and no bottle opener which we have bought of course but just something you would expect. We certainly plan to rent the flat again as we often come to Valencia! Great find
