WARNING! The hotel refused to honour my confirmed booking altogether. When I rang the hotel up to advise about my late arrival the same night (as I was driving from a different country), I was told that they had no room for me! I was offered no apologies, no "sorry", nothing. The reception guy even went to blame me for "not reconfirming the booking before 6pm" (which was neither required nor true as I emailed them the same morning advising about late arrival). Additionally, the guy spoke hardly any English and even basic conversation with him was a nightmare. Terrible experience when at 10pm and on the road you learn that you have no place to stay. I am very grateful to HOTELS.COM staff who stepped in and instantly found me a room in a different hotel in the area without charging a penny. As for hotel Ottersleben, if you think about booking it, BE WARNED!
