The stay went very well. The house was nice, modern and well decorated. The location was super, probably one of the best you can find in Valencia.
Only note: the hairdryer was broken and the bathroom was quite cold (perhaps because of the extractor fan, I don't know). Taking a shower in the cold, in January, and without the possibility of drying your hair, is not very pleasant. It's the only reason we didn't give it full marks, but with a correction from that point of view it's a 5 star apartment without a doubt.
We'll come back!
