Kenny was an excellent host, he always answered any questions we had and even gave us some recommendations for things to do in Valencia. The apartment was perfect and very spacious, I loved the decoration and the terrace was bigger than it seemed in the pictures. It's true that it would be better to move by car but we didn't have any problem with public transport either. You can catch the bus 70 to go to the city center, the 95 to go to Ciudad de las Ciencias and the 99 to go to Valencia's bus station. Also, I think 3 days are too short because we didn't have enough time to enjoy the apartment to the fullest as we were visiting the city, I recommend 5 days minimum, Valencia has many many places to visit :)
