We had a great stay at Carlos and Nerea house. The space was enough for five persons and it was very comfortable. The supermarket was right under the apartment and if you walk further you have a Lidl. We did not use the public transport but for parking it was great! You can park for free on the streets.
One thing to keep in mind is, the living room has an airconditioning but the sleeping rooms have not. but some nights were okay with the windows open at night! No mosquitos :) we would definitely recommend this apartment to our friends visiting València next time!
