I highly recommend Eva's place. It is in a great location, you have shops, cafes, restaurants and all of Valencia's attractions within walking distance. If you come for Fallas, you will be right in the heart of the action!
The apartment itself is exactly as pictured and very comfortable for a short or longer stay (I stayed for 2 weeks). It has everything you could want out of an Airbnb even down to a large selection of spices if you want to do some cooking...but why cook on your own if there are fantastic restaurants around;)
Eva herself is a fantastic host. She was happy to organize transfers to/from the airport, book tours, and made some great recommendations.
