It's a really lovely apartment for a couple. The metro station is one minute walk but if you like biking then the Valenbisi biking station is also just around the corner! The grocery shop is also very near.
Beach is 20 minutes walk and the famous science museum is also around 20 minutes away from the apartment. If you take the bike then 5-10 minutes both.
The neighbourhood is quiet.
Parking is free but like in all Valencia it is difficult to find a spot after 20:00.
The Internet in the apartment is fast and reliable so if you also plan to work during your stay you don't have to worry about the connection. It's superb.
I can only recommend this accommodation!
