The Hotel Domspatz was good!We stayed 2 nights in May and it was good. The rooms were nice and clean, the whole hotel has a nice charme.The good thing is, that it is only a minute away from the cathedral and the main station. Even the Rhine river and the old town are only a short walk. The hotel is located in a less busy side street and during the night there was mostly no traffic. You mostly don't hear any traffic as they have good windows. The surrounding area is nice.The guy at the reservation even looked up for us some train connections where we wanted to go, which I really appreciated. We could have connected our own laptop in our room if we wanted to and if we owned one :-)The continental breakfast was good and fresh. You could take as much as you wanted to.There's someone at the reservation until 11pm. After that you get in with the room key which also opens the front door.Their website is: hotel-domspatz The Maredo restaurant (they have Argentinian steaks and the regularly served meals) right across the street has a great salad bar! I got the tip from the hotel guy and we enjoyed a great salad there.
