When going over to Koblenz in December 2001 (not 2003, but that was the earliest year in the drop-down), I had the problem of arriving on Boxing Day (Dec.26), when most hotels were closed. The only one I had found that was open was Hotel Höhmann on Bahnhofsplatz, and reserved a room by email, which was convenient and a good service. It was an expensive choice for my very limited budget, but the youth hostel (where I had stayed last time I was in town) was closed.
The location was very convenient, as I arrived by train, and it's just a stone's throw away from the train station.
I was given the keys and went to the room, where there were two beds. I had only booked a single room, so was a little concerned I would be charged for a double - or having to share it with a stranger - but they assured me it was in order, and I would only pay for a single room.
The room itself was on the first floor and not very big but had an impressively high ceiling. The window overlooked the back of the hotel.
The hotel seemed quite dated - the room smelled a bit old, but nothing really off-putting. The bathroom was dated as well. I was thinking of having a shower, but couldn't get the hot water to work, for some reason, so gave up the idea. I was going to a different hotel the next day anyway (this was pre-planned before I began the journey), so it didn't matter.
I slept like a log - partly down to having spent the previous night on a bus. The next day, when I was getting dressed, someone knocked on the door and then came in - the cleaning lady. This was my fault - because the room had two "front doors", I thought the knocks I heard were for another room, and didn't answer (plus I didn't understand what she was saying).
Didn't have breakfast there, as that was an additional cost which I could not afford. All in all, perhaps not the greatest of hotels, but it served its purpose.
