Spent 5 nights at the Adina Cologne during a rainy few days in August. The Reception staff were efficient and welcoming. Room size great, with a lovely bathroom.
The hotel is very conveniently located next to the Köln Conference Centre and a short walk to Köln Messe station. We selected this hotel due to the ease of getting to the train station, which allowed us to explore by train, not only Cologne but the wider area - travelling to Bonn, Linz (for a Rhein boat trip) and Düsseldorf (direct trains to the airport). This part of Germany has a fantastic train infrastructure. The hotel is also a short walk to the Lanxess Arena and a superb Italian restaurant is just a two minute walk away (separate review).
This is the third Adina we’ve used (others being Berlin & Hamberg). This hotel has the same in-room facilities we enjoy - a mini kitchen with sink, cutlery & crockery, fridge, coffee machine, oven, washer dryer and mini dishwasher - so well designed that all this can fit into a small space. We usually had a light breakfast in our room, so can’t review the hotel restaurant breakfasts.
One issue with the hotel, typical with many hotels unfortunately, is that only one weight of duvet is provided, usually heavy weight, so you either get too hot at night or sleep under just the cover by removing the duvet itself, and then are too cold. We did ask reception for a summer weight duvet, however they weren’t able to provide one. Would have been 5 stars if not for this.
