We spent 5 days in Valencia and loved every minute of our stay.
Alexandra&Nacho's apartment was indeed the best choice for us. It was recently renovated, very clean, well equipped and close to the Oceanogràfic (10 min walk). The street was nice and quiet. The bus station it's at 100 m and from there you can go anywhere you like.
Thx again Alexandra&Nacho. Hope to come back soon :) .
