Don't be fooled by the professional look of the hotel website and the beauty of the pictures - the reality is nothing like it!!!
The best thing about the hotel is the adjacent stylish beach lounge where breakfast is served, a nice and chilled place, and the breakfast is pretty good.
The hotel itself is 3 star at best. Our room was small and neither stylish nor comfortable. Plumbing is pretty bad - don't try to use the toilet twice in a row as the cistern won't fill up again! As other previous users have mentioned, the room doors slam loudly when closed and the hallways are generally noisy in the night - so is the road outside the hotel on weekends.
The pool is small, set in concrete and fenced in, with no attempt at providing shade for the few loungers or making it pretty with plants or any other accessories. There is a private stretch of beach just across the road from the hotel, but it's rather small and crammed, with the loungers very close to each other and no privacy. The first-row loungers were occupied pretty early in the morning (in late September, mid-season), so after that you are left with a second- or third-row view of your hotel neighbours rather than the sea. Perivolos beach is generally quite busy, with all hotels and many bars occupying stretches of beach, so you can't really find privacy elsewhere either.
All in all, the hotel was a bit of a disappointment, and not really worth the amount we paid for it on Expedia.
