We stayed for 1 month in June and really enjoyed the place.
Positives: Nice location near the beach in a non-touristy neighborhood. Valenbisi, bus, grocery, cafe, restaurant all extremely close. Elevator, A/C in every room. Family friendly home, with several playgrounds nearby. Judith is very responsive.
Negatives: location is not near city center or Metro, so getting to old city or Turia requires a 45-minute bus ride. Apartment building is not new, so we had a few minor maintenance issues that Judith took care of quickly. Balcony is tiny and only useful for drying clothes. This may be common in many older Spanish apartments, but sewer gas smell in bathrooms was difficult to avoid. Housekeeper only gave us one set of sheets for a three bedroom apartment (because we were a couple with a small child), so we had to ask for more later.
