This hotel was immaculate. The converted historical water tower makes for such a unique and stunning experience. The interior brickwork and layout is truly beautiful. The staff was exceptionally friendly and competent and spoke multiple languages perfectly. The facilities were in excellent condition and looked like they belonged in a magazine. We especially loved the complimentary tea and coffee bar and the hot sauna. The rooms were extremely comfortable, super clean, with excellent water pressure in the bathrooms, and even heated floors. The AC also worked perfectly and we had a great view of the city. There is a rooftop cocktail bar that has a panoramic view of the whole city and frankly we liked the hotel so much it was hard to leave to go walk around the city! Would recommend this property to anyone.

We knew when we booked it that it would be a little longer walk to the historical old town center of Cologne, but the walk was easy and worth it to stay at this property. There are fewer restaurants in the immediate viscinity but plenty of places within an 8 - 10 minute walk.

Really interesting place to stay. Liked the lounges on the ground floor as a place to hang out and have a coffee or tea. The bar was nice when it wasn't busy with great views over the city. The room was very nice but way too hot even without the heating on we had to have the window open the whole time and take off the duvet!

The bar was so busy on Saturday night that we couldn't get a drink which was a shame as it was my husband's birthday and couldn't make use of a free drinks voucher either (a nice system if you don't want your room cleaned is that you get a voucher but we couldn't use it).

Unusual building, converted water tower, beautifully designed inside with very comfortable and well designed bedrooms and bathrooms. The beds are very comfortable. The breakfast was delicious. The reception staff were really excellent. We had a lovely welcome when we arrived. Unfortunately the heating didn’t work in our room so a heater was instantly provided for us,and when the engineers were unable to fix it the next day we were offered an alternative room which we declined as the room was warm enough with the heater. So we were offered a free drink in the bar, and the next evening a beautiful bottle of wine and delicious macarons were delivered to our room by way of apology. Totally unnecessary but very thoughtful and very much appreciated. Many thanks to reception for looking after us.

The rooftop bar is amazing but could do with more seating

The location is good, 10 min to the conference on Taxi and 10 min walking to the center of the city. Very comfortable beds. Nice roof bar with amazing view, breakfast is good as well.

I stayed in the room that had a door to another room. Whenever somebody was talking in the adjacent room, I could hear everything as if it were in my own room. It was a disaster when a drunk couple returned from a party at 3 am; I had to go to the reception. Fortunately, they managed to calm them down. Additionally, my plans changed, and I had to leave one day earlier. I had requested compensation for this change two months in advance. However, the management wasn't helpful at all; their response was essentially, 'You have a non-refundable booking, f#$k off, what else you want'. But in situations like this, it would have been nice to be offered a room upgrade or at least a drink. Unfortunately, they offered nothing

Original, 'insolite'. Close to the city-center. Well-equipped spacious room, very nice view over the city of Cologne. Great breakfast, although quite expensive (31 euros per person).

Noise in our room on 10th floor - due to roof-top bar just above n 11th floor, with quite a bit of 'boom-boom' until 1 o'clock. Expensive and narrow garage, with unclear getting-in and getting-out instructions ( creating a lot of unnecessary stress)

The hotel itself is very special. The old water supply tower is built as a very solid brick building and was converted to a hotel. It has a lot of quirks when it comes to the hallways, but that’s part of the charm. Rooms were clean and spacious. The roof top bar was outstanding and is worth a visit even when you’re not staying at the hotel.

Check in and check out were slow. They could use some more staff or a bit more “speed”. The location itself is a bit off the beaten path. Nothing noteworthy is in walking distance really. However that it to be expected with a hotel located in an old water supply tower.

The room was very cool, comfortable and clean. The staff were very friendly and reacted quickly to replace the television that was broken when we arrived.

The rooftop bar was useless, the took 45 min to bring cocktail with half the ingredients missing, never had the wine we ordered, half the food menu was unavailable. We visited twice and the poor experience was the Sam both times. The bar let the hotel down. all the streets around the hotel up to Neumarkt had hundreds of drug addicts and homeless people taking drugs openly and defalcating in the street. It was unpleasant to walk anywhere and we had to take taxis to avoid the disgust.

The property was very beautiful…hard to imagine it was once a water tower! Such an incredible place to stay and while it was not right in the city center, it was an easy walk to get there. We loved our room (with its spiral staircase leading to a loft with the beds!) and were welcomed with a handwritten note, some truffles and a small bottle of wine. It was the perfect stop for the last night of our vacation…very memorable!

Hotel is a an old beautifully converted water tower. For any architecture lovers its a great place to stay. Rooms are very well presented with free wifi throughout. Breakfast was great with a good selection of options from hot, cold & continental. The bar on top was great too.

Hard not to like anything. The only let down was one of the days my room wasn't cleaned but this wasnt too much of an issue in the grand scheme of things.

A very unique experience with Hilton. Staff are very friendly and courteous, with smile on their faces. A fruit plate and two bottles of spring water delivered to the room were a great thought. It certainly added delight to my pleasant stay. Besides, the great room configuration is more like a studio. There is a good-sized dressing area between the entrance and the bedroom, whereas most hotel rooms have just straight corridors, instead.

Wouldn't want queue for the slow lift at busy checkout time
