We had a great time at this apartment. It's close to both train stations and the main metro hub so arriving and leaving is really easy. Almost all interesting areas of Valencia are also within walking distance.
Beds were comfortable and the blankets were really nice and thick, kitchen had all the necessary amenities.
You will also get a long list of possible things to do and restaurants to eat at.
This is an apartment in the city center so light sleepers might want to take ear plugs with them (at least during weekends)
