Location is great - well within walking distance of the city center and the park. Eating and shopping options available nearby. Quiet apartment building with an inner yard, very useful for keeping your rented bikes in a safe place. Spacious interior with separate toilets/bathrooms.
Host was very patient with us (our flight caused a 90min delay for check-in and Carmen waited for us on location nevertheless), and very helpful (booked us a 5am taxi to the airport for our return trip).
I would recommend this listing and we'd consider it for our next trip to Valencia.
