The flat is great with a superb location! We loved the terrace, especially the string lights for a lovely place to hang out at night. The bed was very comfortable. One complaint is it feels very stark and lacks personality. There were quite a few mosquitos which come in through the screenless open windows. However, the breeze was too nice to resist having them open.
We loved being on this quiet side street with a park where locals seems to stroll at the end of their work day, or feed pigeons, or chat with friends as they grab a coffee or drink at the local coffee stand at the corner. There are a few cafes to the adjacent street to the right, and tapas bars and a delicious bakery called Juliet for scrumptious, warm cookies and cinnamon rolls to the left. If you have car and need parking, the parking garage at Glorieta-Paz is super clean, easy and convenient. Groceries and prepared foods are available in the Corte Ingles, the next block over. Overall, it's a clean, safe, spacious, convenient and utilitarian place to stay in Valencia, just don't expect any extras.
