Fabulous location, just 2 minutes from the cathedral, Plaza Reina etc, and 5-7 mins to the Turia riverbed and Alameda subway. It overlooks the very pretty San Esteban church.
First class bathroom fittings - it felt like the bathrooms were brand new.
Overall a very stylish apartment to stay in, and it easily takes 4x adults and a small child in the supplied cot.
Re the noise - staying this central in any city is always going to have some outside noise. There is no noise from other tenants in the apartment block itself.
What a cool, stylish place Valencia is too - we wandered around the old town, Colon, rode bikes through the Turia, visited Cuidad Artes & Ciencas, and spent a day on the beach. Amazing 4 day holiday.
