We stayed with the family around New Years Eve in the apartment. Good location and good apartment. Especially the terrace. Only 10-15 minutes walk to the city center and nearby the metro. Also enough restaurants in the area.
During the weekend it is very noisy because of the bars/clubs downstairs. And we had problems with warm water with 5 adults. It was impossible to shower in the 2 bathrooms at the same time.
But we had a perfect stay in Valencia.
