Had a fantastic stay at Carlos's apartment - i have stayed in dozens of airbnbs and this was probably the best. The apartment is modern, spacious, very comfortable, well laid out and very very clean. We visited in winter and the heating worked perfectly too. Great location in the old town and beautiful views from the balcony and windows. The hosts are very kind and professional, were quick to respond to our questions and kind enough to share a lot of information about the town. A very strong recommendation from us to stay here if you visit Valencia!
