Stayed here for the weekend to take advantage of the cheap weekend rate, but I decided to move somewhere else after the weekend as I wasn't too impressed.
My room was spacious and comfortable enough, but the furniture looked dated, in fact most of the hotel, and especially the lobby, feels like it is still stuck in the '80's.
Despite the atmosphere, the food in the restaurant was very nice and I thought good value for the area. Unfortunately this was let down by flies, which bothered me each time I ate in the restaurant. This was in December, so surely not from outside, suggesting some problem in the hotel. I mentioned this at check out and was told they are aware of it but haven't been able to solve the problem yet.
The main reason which led to my departure from the hotel was the wi-fi, if a hotel charges you for wi-fi you should expect a decent speed, unfortunately it was woefully slow here.
The lack of on-site gym was also another let-down.

The hotel is somewhat tired however the price reflects this. it is very clean. rooms are large and the staff are super friendly and helpful. The tram is a one minute walk and you can be in the old town in ten minutes,

Has a small indoor pool however it doesnt allow children under 4 in the pool ??? . We had to sneak our kids in and the staff turned a blind eye

We stay in Dusseldorf several times a year and this will be our only hotel from now on.

I have stayed at this hotel several times over the last 10 years whenever I attend ANUGA, the world's largest food exhibition in Koeln. I stay in Dusseldorf because I prefer it to Koeln (Cologne). And I stay at the Renaissance because it is simply far superior for the money than any other hotel I've tried in either city.

Service is superior. Breakfast is superior. And the rooms are comfortable and quiet. I've always wondered about the location, though, as it seems located in an odd place. Although a short drive from the Dusseldorf airport, it does require a tram ride to the train station or downtown. Nevertheless, the tram stop is a short walk from the hotel; it only takes 10-15 minutes to downtown and it provides a moment to relax and enjoy the neighborhoods. Great if you're a people watcher, too! There is an excellent tratorria (Italian bistro) just around the corner.

I would recommend this hotel to family travelers as well.

I stayed here in September 2010 (in the bottom November 2010 since I cannot select a period further back in time) with my mom after i did an internship here for 6 months in 2008! It was great to be back, now as a guest. The rooms are very spacious. The breakfast is amazing with so many choices that you cannot complaint. Staff is helpful and attentive. The location is a bit outside of the city centre, but within 15 minutes with the public transportation your in the middle of the Altstadt, shopping area etc. Great stay-over for a trip to Düsseldorf.
