I have stayed in the apartment for 1 month in December'15. It looks new in every room, everything is fresh and clean. The internet, air conditioning, TV, stove, etc work as expected. The owner was very responsive and brought some additional stuff I needed (e.g. a clothes drying rack).

The location is great for long-term living. It is a bit off from the Old City, but still very close to the big Turia Park with the City of Sciences and other landmarks (10min walk). The park is especially good for running (7km in one direction) and bicycling. The public transportation is there - buses, bicycles, metro - though I preferred walking around. Of course, there are a lot of restaurants (check TripAdvisor) and different shops nearby; the Mercadona supermarket is just around the corner.

Greatly recommended.
