Superb location, really nice little area and easy to get to all main Valencian attractions. We really enjoyed this. Was a little noisy in the evenings but as expected for location in middle of a city. There is no parking nearby, this would be same wherever you stay in this area though. The apartment itself was bright, airy and spacious. It is perfect for a couple for a 1-2night stay. The locker facilities, which are large (but do need 1 euro coin) are really helpful to leave items prior to check-in/check-out.
The towels were really poor, consider taking your own. Only 1 pillow per person. Shower area needs some replacement flooring but apartment was clean on arrival. Could do with more items in kitchen to increase its usability. Things like extra dishtowels, things to clean-up / wipe with would have made it easier live there.
We did visit with a toddler, so may have been adequate enough if just adults. A few small and easy improvements could make this place a lot more easy to manage in day to day.
