My wife and I stayed at the Wartburg Hotel for three nights. The hotel is in a quiet and convenient location but near plenty of shops, restaurants and the U- and S-bahnsand. Koenigstrasse, the long pedestrian street, is a short walk away. Our room was quite spacious and well furnished with art deco furniture. Breakfast was very good, with lots of choices. The staff were always very friendly and helpful. We had laundry done there, and it was done within the same day. The only complaint would be the lack of air conditioning, but otherwise a very nice hotel.
