I've stayed there a couple of times, I wouldn't say it's pretentious, I just found it very over-priced for what it was - essentially a bog standard hotel room with no extra facilities, just a Hed Kandi poster above the door.
If you do a search for Es Vive you'll find lots of reviews on it, me personally I wouldn't stay there again as I feel there are way nicer places to stay for that amount.
