The pictures make this look much nicer than it actually is. Overall this is a very low end stay. It is fine if you simply need a bed, however, we felt a bit deceived by the appearance online to IRL.
The bathroom had several problems (shower head was broken and sink did not drain). This is a hostel - many other guests stay here as well. Keep this in mind as the noise level varies depending on your neighbors.
One positive of this place is the location - very walkable to some of the best parts of Valencia. You must go to the Cental Market - such a neat experience.
