I would highly recommend Rafa& Jorge's apartment! The location cannot be beat! Do not miss the St Nicholas church... Also known as the Sistene Chapel of Valencia!
Even though the apartment is in El Carmen neighborhood, it's very quite!
Rafa met us when we arrived and helped us order a taxi when we left. The beds were comfortable and all the basics (including milk, coffee, water, soap, etc) were already there. Overall, I would definitely recommend and would stay there again! We loved Valencia!!!
