Everything was OK.
1 if you come by car it is very difficult to access but you have parking under the central square ... central market parking, cost per night between 8 pm and 5 pm 5.5 euros.
In Valencia parking on the blue line maximum 2 hours after the fine 30 euros, only on the white line is free but in this area there is not much.
2 excellent accommodation position right in the old center, hundreds of terraces and bars, time to have.
