The apartment was absolutely lovely! We really enjoyed the roof-terrace and the whole apartment was superbly equipped and very homely decorated. The description on airbnb matched what we found and even surpassed our expectations. The flat is a 3 min walk from the metro in a quiet and authentic middle/working class neighborhood, nicely situated between the city centre and the beach with a supermarket just around the corner. Erika was very professional and detailed in her communication. Hector, the guy welcoming us, also deserves a special mention as he was so nice to come pick us up when we were lost and couldn't find the flat upon arrival, since street names change in Valencia along the same road. He was very friendly and always available for any questions.
I can really recommend staying at Erika's lovely place and we might be back too.
