We loved staying at Amalia's place, the photos don't do it justice! It's a short walk into the town centre (approx. 15 mins) and just round the corner from the train station which was ideal for us as we were travelling to/from Valencia via train.
Valencia itself is lovely, we'd recommend renting bikes to get around as there are lots of cycle paths so it feels very safe and it's a great way of getting to the beach or exploring the 'river'.
There was two of us and the flat was a perfect size, it felt spacious, we spent our mornings in the flat as the terrace is such a good breakfast spot! There's a supermarket just around the corner and a few cafes nearby but we mostly went into the town centre for bars/restaurants in the evenings.
Would recommend staying here!
