An excellent hotel, staff were very friendly and efficient. The room was clean and tidy. We did find the glass partition unusual between the bathroom and bedroom, a bit odd showering and being to see in to the bedroom and vice versa, didn't bother us that much though.
We only ate breakfast at the hotel, there was plenty of choice, including continental meats, cheeses, bread olives, pickles, also bacon, sausage, egg, beans etc, cereals, fruit, yoghurts, pastries. My wife was particularly pleased to see that both oat & soya milk were available as an alternative to cows milk.
The hotel is ideally situated, within a hundred meter radius there is Cologne cathedral, a german/roman museum, modern art gallery, the Rhine, old town square, main shopping streets, and many restaurants and bars. If you want to explore the region more, the main train station is also only a five minute walk.
We'll definitely be staying there again.
