Do not book there - they scam people! And delete reviews! I booked a room and shortly after that I got a notification, that this room is actually not available. I asked for the money I already paid, but did not receive an answer. Instead of the refund they gave me another room and shortly after (!) the booking I received a message, that I need to pay monthly bills (90€) extra (!), which where not mentioned on the website. I cancelled within 24 hours (like they write in their terms and conditions). They wont pay me my money back. I needed to contact lawyers, my bank and different commissions. Furthermore I reported the case to the police department. Now I am waiting for the result of this process. 
I informed my university in my home-country and hope, that people wont get scammed anymore.
