I would say excellent for this hotel. Feels like staying at 5-star hotel.The staff are very helpful. Rooms are very clean and have large area especially toilet! The facilities in the bathroom are great and clean. Also, the location is quite near the train station in 10 mins walk. Really recommend this hotel if you come to Cologne.
I booked a place in a dorm room. So shared with three other people in 1 room. It's nice in a room like that to get to know or chat with other people in that room. It's okay, it's the place. [+] ] below (ground floor) there is a desk, where you can study/work for 24 hours. [-] ] some some long empty, although not in the middle of the night.
When we just came, the lift was under repaired. It cannot be used to bring up our big luggage to our rooms. So, we have to use stairs and lifted our luggage. But, the location of this hotel is very convenient, very near to train station, a lot of restaurant or cafe to spend the time.
