A beautiful building directly opposite an aqua park and a short 10 minute walk to Neuplatz. The area immediately outside was quiet.
Nice spacious room (king junior suite on 3rd floor) with a comfy bed and a view of the aqua park.
The lighting level of the room was a little low for my preference, even with all lights and lamps switched on. The bed was comfy but I did later notice that the quilt had a stain on it. One day, I was only left 1 bath towel. I could not get the phone in my room to work.
The breakfast was very disappointing. I went once at 09:30 and the buffet items had all but been taken so had to wait for replenishments. I opted for a more expensive hot breakfast (31 euros) but nobody came to take my order.
The room service menu was disappointing, especially given that the only other dining option was bar snacks in the rooftop bar. I did eat there one evening and found that the service was good, and whilst a restricted menu, the food was hot and delicious, and I enjoyed a cocktail.
There was often only one receptionist at the desk so you tended to have to wait to ask a simple question. They were professional and helpful though. The lobby was compact but visually impressive.
The spa (5th floor) was disappointing in that there were no staff, no lockers or changing rooms. There was a nice relaxation area with loungers and a nice, clean, spacious sauna. There was no steam room.
Cologne is a beautiful, friendly city.
