Standard disclaimer: This review is affected by a bad personal and seasonal experience. The hotel is listed as a four-star hotel and while surprisingly Spartan for such, it is clean, modern and at least my room was good-sized and well outfitted. The staff speaks English and the location close to the southern end of Königsallee is excellent, whether you want to go for a stroll or use public transport. The surrounding restaurants are of varied cuisine and generally of good quality.
Then the bad.
There is no air-conditioning in the superior rooms, despite a control unit mounted on the wall. Düsseldorf can be downright tropical in the summer and the room got so hot that not even the minibar fridge could keep its contents cold anymore. You have to keep both windows open and while the hotel is generally quiet and well-soundproofed, the streets and restaurants outside are not.
My booking at this hotel during summertime was a mistake, plain and simple, and the hotel staff simply had no answer to the suffocating heat. I could add a minor complaint about the hotel wifi, which was unstable and at times downright weird.More
