Good location especially if you need to be close to the station. A short walk through the station takes you to the Dom and on to the main shopping area.
The room (a single) was clean, in quite a modern style and I didn't hear much noise from outside or other rooms. Nice hot shower and the hotel provided shower gel, body lotion, a nail file and sewing kit! Breakfast was served from 6am to 10am a great selection of cereal, fruit, bread, spreads, fruit juice, coffee and tea. There are also hot food options, but I was pretty full on just the continental. The breakfast room has quite a pleasant outlook too.
Reception staff were professional, polite and helpful, treating my attempts at German with good humour.
If I go back to Cologne I'd definitely stay here again.

Stayed there 1 night during our 3 week Europe honeymoon. Not our planned hotel, but since our train was delayed and there is no connection to Braubach (our original hotel), we just walked up to the front desk and asked for a room.

Paid 99 Euros (total, including breakfast and tax). Room is basic, beds are ok, a bit hard compared to our previous 4 star hotels, but I had no trouble falling asleep. More like a "motel" in the US standard. With the windows closed, it is quite. Otherwise, you will hear road noise (no big deal for me).

In a nutshell, not a bad place to stay at all.

Don't be put off by the exterior photos that make this hotel look like a stranded remnant from the concrete architecture of East Germany. Inside, the hotel has been modernised, is in excellent condition and is very clean. Although the rooms are not huge, they are perfectly adequate and the location, about 50m from the main station's exit, cannot be bettered. Part of a small chain in the lander of North Rhine Westphalia, this is a good 2/3-star hotel offering value for money, but without a restaurant for evening meals and only a small lift. It's not luxury, but is a perfectly good tourist and business hotel that can be recommended.
