BEWARE OF THEIR SCAM! Don't believe me?Read other reviews (I should have!), this scam goes way back. You will pay in advance for a 4-star hotel, you will arrive at that hotel, they will begin checking you in, then they will inform you that they're all booked up but they are "upgrading" you to a "Acropolis view" at their sister hotel (or whatever their game is that day), cab ride is on them! They will usher you out of the hotel to wait for your cab.
You will show up to a shabby, run-down, at best 3-star and have to argue your case there. Don't bother asking to talk to the manager, they will conveniently be unavailable between the time you check in until half an hour after you need to leave (quote, as our cab was getting loaded up: "just wait 30 minutes and our manager will be here").
Note: if you have accessibility needs, the sister hotel is not accessible. They don't care, they already have your money.
