Not much to add to the existing reviews.
Stayed in June (25oC) flat was cool with barely the need to use the air on.
Great flat in a super location, very quiet but close enough to all amenities, bars and tourist area.
Very much as described (if not quite as light as the picture would suggest, not unusual given it is on the 1st floor)
The old town is the best location to stay in.
Miguel made life easy by meeting us at the airport.
Highly recommend.
Valencia is a wonderful city.
