This is a terrific apartment, very clean and super stylish! Easy check-in, and a great location close to the train and the center of the city. I would try to book this place again if/when I return to Valencia. Small but great for one person or a couple.
Only note: the wifi was a little slow, so I'd check on that if you have important work to do. Also, if you're above 5'10' / 180cm or so, you're just going to hit your head on the big wooden beam in the loft in the middle of the night no matter how much you try to remember it, haha. No sharp edges at least, so you can curse yourself and be fine.
