"I really enjoyed my stay and although it was 30 minutes train ride from Berlin HBF station, it was still very convenient. The rooms were lovely, clean and modern. I never used the restaurant facilities, so I cant comment on that side. I didn't want to pay 21 euros for breakfast with a limited choice of hot food. There was a 7 euros(ish) per day, city tax to be paid on check in.
My stay was to explore Berlin and after a long day sightseeing the hotel location was actually really nice. The local village, just a short walk around the corner was lovely to wander round, get a coffee or alcohol, a bite to eat, ice cream or general shopping to pick up a few bits. I tried two Italian restaurants and the food was lovely.
The Hotel location was across the road from the station and just 2 stops away from the Olympic Stadium (5 mins). Trains were very frequent with two trains, the S3 and S9 taking you to and from Berlin and often every 10 minutes. They seemed to run till quite late too so no need to feel you had to get back early from Berlin."
