It's not a 5-star hotel, but price/quality is very good.
The mattress was quite too squeaky, otherwise everything was fine. The apartment is on the 12th floor and the view of the North-West part of Valencia isn't obscured by other buildings.
There's a table where you can work quite comfortably with you laptop.
The room can only be locked from inside, there's no individual room lock.
There's quite a noisy busy street in front of the building, but when you're tired enough, it's not a problem at all :)
