Absolute scam - they are mimicking an authentic hotel web site. I booked on March 24 with free cancellation until April 27. When realizing that they only add fees I made a cancellation within 30 minutes. Their automated response: You have paid the full amount and there is no refund. I have informed my CC on this fraudulent behavior providing screenshots of every step. Such a shame. I am confident to recover the 380€ (415 USD). But it made me really upset and had a bad sleep.
