25hours Hotel The Circle 4 stars

OK so let's start this review: - we spent 2 weeks in the hotel (it was a work/travel trip) - we had a large room and it was simply AWESOME save for one big big big problem for us: the ventilation was so unbearably loud that we had to switch rooms and figure out how to turn it off in the other one. When I say loud, I mean that the employee himself asked me if this was the sound of someone taking a shower in the upstairs room. This was not OK for us but we overcame this issue by turning off the ventilation. - The coworking space/café is absolutely STUNNING, as is the reception itself. You get working pods where you can totally isolate yourself for calls and wonderful coworking spaces that are accessible by the hotel clients and regular city dwellers. - The restaurant has a great view with some good food. It is very very very busy most days. It's a restaurant that is very hyped and for good reasons but we tend to prefer quieter places. Is this a complaint? No! It just means that if you come here expecting to be able to waltz in without a reservation, you are in for a big disappointment. - The sauna is big, spacious and super enjoyable. The view on the cathedral is unlike anything you could hope to have in any other hotel. - The staff is super sweet and efficient. I was very impressed with their ability to overcome long lines of check-ins, check-outs, folks with questions, etc. - The WiFi is not great when the coworking gets too full. We had issues making business calls in our room and in the coworking space which was problematic twice in a 2 week trip. Take this with a grain of salt, it doesn't mean YOU will have issues, we simply had 2 glitches during the whole trip. Overall, would we stay in this hotel again? ABSOLUTELY! It is quiet, calm, comfortable and with a gorgeous, gorgeous GORGEOUS interior design you won't find anywhere else. Cherry on top for us: it was centrally located.

Plus: very good shower, parking garage at hotel, rooftop bar, ueboom speaker at the room, beds, special design. Minus: airco did not work very well, no chairs at the room, nothing to put suitcase on, no cupboard, noisy.

This Hotel has managed to go straight to number #1 of my personal top 10 list. Excellent service where it mostly counts, when things go wrong! Fantastic design and spacious rooms, excellent cocktail bar over the rooftops of cologne and the Neni Restaurant(oh the Food has been a culinary experience, which should be on everyone’s bucket list!!!) Thanks Carsten, Sophia, Marc, Manuel and all the others that made it this an experience to remember for life! Kudos 25Hours Teamwork

Funny and nice hotel. Restaurant is good. Decoration is directly from the space odisey of the 70's. I am used to travel a lot and this one changes from the usual ones. Co-working space is interresting, especialy because you have few space to put your computer on the bedroom table.

Very nice new hotel, with confortable and quiet room.Design is present in every details.The bed is very confortable and pillows are ok.Breakfast is quite expensive if not booked in advance.The restaurant Neni is already quite popular and booking in advance is needed for evening.
