The hotel has a nice veneer. On the surface, it appears well-apportioned with all the ysual amenities. However, just about everything is just a bit off. Parkibg (as mentioned by other reviews) is a mess. We got in but couldn't get into the hotel section of the underground lot. The check in girl had to come down to open the internal gates. Leaving was even worse. The hotel doesn't have a night staff and when we tried to leave at 6 am, the pay kiosks didn't work. We had to wait a half an hour for someone to show up. Fortunately, we had built in extra time to drive to the airport in Frankfurt.
The hotel is not in Köln proper. Expect to drive to the city, grab an Uber or figure out public
Thewas big and clean but furnishings were dated. The a/c was functional. The 3rd bed (cot) leg had a nasty habit of collapsing. The shower wand holder was broken and there was a leak under the tub.
The breakfast was good. Probably the best scrambled eggs I had in Europe. The restaurant attached (not part of the hotel) had excellent sauerbraten and dumplings.
The vending machine also didn't dipense product paid for. The desk clerk also couldn't get it to work.
The staff was attentive and did what they could but you coukd tell they've been dealing with these issues for a long time. There is a nice bar set up in the lobby but I never saw it staffed.
All in all, the hotel served it's purpose and none of the issues ruined the trip but with a few tweaks, the hotel could be very nice.
