Stayed early December 2010 for one night. Hotel is in the south of Berlin and was about a 30 minute taxi ride from Tegel airport (cost 35 euro) - but was close to where I was visiting. It is not in the centre of Berlin.
Room was OK although the electronic key took some getting used too ! Free wifi is available but i could not get a decent signal in the room - but was fine in the bar / restaurant area. Breakfast was fine - typical continental buffet. All in all a pleasant stay.
