My wife and I visited our daughter in Koln who was going to school there. We chose Renaissance because of the Marriott connection. The staff was exceptional, the room was roomy, clean and comfortable and the morning breakfasts were wonderful. When we return to Koln we know where we're going to stay. Its a short underground ride to Der Dom from the hotel
excellent hotel and close to the Christmas Markets; only problem is I did not get my reward points from Merriott! Rooms were very nice and the beds were excellent!
