We had a great time at the appartment which is located perfectly between the city center and the beach. The metro station is just a 3 minutes walk away. On top a supermarket is right at the corner and many nice bars and restaurants are directly in the neighbourhood.
The appartment was clean and made us feel comfortable. We were not missing anything. The communication was very good and quick. So we just can recommend to stay there if you want to have a great home in Valencia.
